The Application of Unmanned Marine Vehicles to Maritime Rescue - John DalzielVR Marine Technologies
The technology supporting Unmanned Vehicles - land, sea and air - is rapidly improving. Unmanned vehicles are making large inroads into Search and Rescue (SAR) response. In the near future, Unmanned Marine Vehicles (UMVs) will likely play a role in Maritime SAR response. Do UMVs have a potential role in Maritime SAR Systems, and if so, what roles could they fulfil?
This document provides a student proposal for marine management of the Sargasso Sea. It begins with an acknowledgements section thanking mentors. It then includes sections on the scientific background of the Sargasso Sea, current governance approaches, key biodiversity targets, stressors on the environment, fisheries, maritime traffic, and recommendations. The recommendations propose designating specific management areas in the Sargasso Sea and implementing tools like marine spatial planning and marine protected areas to balance conservation and human uses. The document aims to inform management of the unique but vulnerable pelagic Sargasso Sea ecosystem.
This document summarizes various operations being carried out by the US Navy in January 2011 to execute the Maritime Strategy. It discusses examples of operations demonstrating forward presence like carrier strike group flights in Afghanistan and amphibious ship deliveries of Marines. It also discusses deterrence like a destroyer deployment, power projection like a carrier strike group exercise, and maritime security, humanitarian assistance and disaster response, and building maritime partnerships through various cooperation efforts. It concludes by providing statistics on Navy personnel, ships, aircraft and Sailors deployed in different regions.
1. The document discusses strengths and weaknesses in maritime risk assessments. It notes that while risk assessments provide structure, they involve simplifications and limited data that affect accuracy.
2. Early risk management involved regulations like bans on winter sailing and strict ship loading rules, showing risk assessment is not new but has evolved.
3. Human factors are significant in accidents but difficult to assess, and models have limitations in estimating probabilities and consequences given changing conditions.
V8 Supercar Race, Sydney Olympic Park and Waterbird Impacts.Dr Stephen Ambrose
The document summarizes the results of waterbird surveys conducted before, during, and after a V8 Supercar race event near the Waterbird Refuge wetland in Sydney Olympic Park. The surveys found that waterbird species richness and abundances were similar across survey periods and showed expected daily and tidal patterns. Numbers of key species like teals and shorebirds at roost were generally stable or higher during the race event compared to before. This demonstrated that the race event did not significantly disturb or impact waterbird use of this important habitat.
This document summarizes a presentation given by Allan Schwartz from the Australian Maritime Safety Authority (AMSA) at a national conference on risk management. It provides background on AMSA's role and responsibilities, which include maritime safety, environmental protection, search and rescue, and responding to incidents at sea. It then discusses AMSA's risk assessment and management approaches, including identifying and mitigating risks through activities like vessel tracking, inspections, and emergency towage. Finally, it examines high profile incidents that AMSA has responded to, such as the search for Malaysia Airlines Flight 370, highlighting lessons learned.

Spatial planning: towards a new approach in fisheries managementTommaso Russo
This document discusses spatial planning approaches to fisheries management. It notes that tracking devices like VMS have revolutionized the ability to monitor fishing activity in space and time. Several Italian research groups are working to develop spatially explicit models and tools to integrate these data into fisheries science and management. One such model is SMART, a bioeconomic model that simulates catches, revenues, costs and gains under different fishing effort scenarios to evaluate impacts on resources. The document examines case studies applying these approaches for species like hake and in areas like the Adriatic Sea.
Editorial – July 2010
Greetings all,
This month’s newsletter is devoted to recent studies in coastal oceanic systems.
To start with, Le Traon is introducing this newsletter telling us about the SNOCO initiative.
Scientific articles about recent studies in coastal oceanic systems are then displayed as follows: First, Ménesguen et al. are telling
us about Ulva mass accumulations on Brittany beaches and remedies found to solve this problem. Then, Ardhuin presents his
work about wave hindcasting and forecasting at Previmer within the European project “Integrated Ocean waves for Geophysical
and other Applications”. Third, Faucher et al. provide a description of a coupled Atmosphere-Ocean-Ice forecast system for the
Gulf of St Lawrence in Canada, which has been installed in experimental mode at the Canadian Meteorological Centre. Finally,
Marchesiello et al. are talking about regional ocean forecasting and downscaling strategy at IRD for coastal and submesoscale
phenomena. They have developed a downscaling strategy based on the Regional Ocean Modeling System and produced a new
demonstrator with data assimilation in the Chile oceanic area.
The next October 2010 newsletter will display papers about the Marginal Seas in the MyOcean project.
We wish you a pleasant summer!
This document summarizes a proposed research project called CESAR (Coastal Environment under Sargassum crisis). The project aims to provide knowledge and tools to help manage Sargassum influxes in the Caribbean region, particularly the French West Indies. It will involve monitoring and forecasting Sargassum distributions using satellite data and ocean models. The project is led by a consortium of research organizations and will have two work packages. The first will focus on satellite monitoring and developing forecasting capabilities, while the second will examine governance and policy related to Sargassum management. Expected results include improved detection algorithms, transport modeling of Sargassum, and policy recommendations to help decision makers address Sargassum
Remotely sensed data of sea surface temperature, chlorophyll, and wind patterns from satellites are used to locate Potential Fish Zones (PFZ) in Indian seas. Satellites and instruments like sonar and radar are currently used to find areas where fish aggregate. In the past, PFZ forecasts were based solely on sea surface temperature maps, but now also incorporate ocean color data from sensors to provide information about conditions below the surface. The Potential Fishing Zone advisories generated from this remote sensing data have benefited fishermen in India by reducing search times, saving on fuel and labor, and increasing incomes.

The document summarizes the development and objectives of the Os Miñarzos marine reserve in Galicia, Spain. It was proposed by the fishers' organization in Lira-Carnota to restore overexploited stocks and limit access through territorial users' rights. The reserve uses no-take zones, a marine protected area, and open-access areas in an experimental, adaptive approach to evaluate alternative management models. Ongoing monitoring evaluates the effects on biodiversity, fishing activity, and potential spillover between zones.
This document analyzes data from a citizen science marine survey program called Seasearch to describe the spatial distribution of pink sea fan colonies in southwest UK coastal waters from 2001-2012. It finds that pink sea fan colonies are concentrated in some areas but also exist outside of existing Marine Protected Areas, potentially putting them at risk from bottom-towed fishing activities. The analysis demonstrates how organized citizen science data can help inform broad scale patterns of biodiversity and assesses whether the locations of pink sea fans match up with areas that have legal protection from bottom-towed fishing gears.
C-SIGMA proposes a collaboration between countries to leverage space-based Earth observation systems for global maritime awareness. These systems include synthetic aperture radar satellites, electro-optical imaging satellites, individual vessel transponders, and automatic identification systems. No single country has sufficient resources to fully monitor maritime activity and protect resources alone. International cooperation integrating these four types of space-based monitoring systems could help countries achieve safe, secure, and sustainable maritime operations and conservation of marine environments and resources in a balanced manner.

Analysis of CPUE and Fishing Capacity of demersal fisheries in Kema 2, North ...IJAEMSJORNAL
Capture fisheries should be a sustainable economic activity aspect to provide good benefits to future resources. Sustainable marine fisheries resources exploitation requires a utilization rate lower than their availability. Therefore, the exploitation rate should not achieve the recovery ability of the resources in certain time. In fishing activities, for instance, there is a guideline not to catch fish over the Total Allowable Catch (TAC), 80% of the MSY. Information on the potency and the fishing capacity of tuna fisheries can be useful for the sustainable management of the resources. Also, this information can be used as a consideration for further management of the potency. There are two purposes of the study: (1) to analyze the CPUE (catch per unit effort) of demersal fisheries in Kema 2, North Sulawesi, for prediction of their potency, and (2) to analyze the efficiency of fishing capacity of the demersal fisheries in Kema 2, The study was done in two stages. The first was done by analyzing the potency using CPUE method (Shaefer models) to obtain the MSY, optimum effort and TAC (total allowable catch); and the second was done by analyzing the fishing capacity of demersal fisheries using DEA method to estimate the efficiency level of the fishing boats and devices in Kema 2. The result showed that the potency of demersal fisheries in Kema 2 was 71,700 tons per year and the optimum effort was 72,964 trips. Fishing capacity in demersal fisheries occurred in Kema 2 for the last 12 years was inefficient, especially for 2001. This may be caused by some factors such as trip operation, fishing duration, oil consumption, crew and operational cost. So, to manage the demersal resources in Kema 2, the TAC should be 57,520 tons per year. Based on the result, to increase the fishing efficiency, we should take into account of above factors. We suppose that the good means is reducing trip operation, fishing duration, oil consumption, crew and operational cost.
Marine growth assessments are important for effective management of potential environmental impacts and financial risks during offshore structure decommissioning. Assessments provide information on added weight from growth, presence of protected species like corals, risk of invasive species transfer, and waste management implications. An assessment found over 2,000 tonnes of growth including corals on a platform in deep northern North Sea waters, while shallower south North Sea platforms averaged 39 tonnes of growth. Assessments support regulatory compliance and cost-effective planning of structure removal and disposal.
Interactions and space-use overlap between satellite-tracked blue sharks and ...ecologiaazul
This study used satellite tracking of blue sharks and vessel monitoring data from longline fishing boats to analyze interactions between the two in the northeast Atlantic Ocean. 32 blue sharks were tagged with satellite transmitters and their movements were mapped. 103 longline fishing boats were also tracked over several years. The results showed spatial and temporal overlap between some of the sharks and fishing locations. Specifically, 5 of the 17 successfully tracked sharks spent at least one day in areas with longline fishing activity, with one shark spending up to 3 days in risky areas. Two sharks were actually caught by surface longlines during the study. This analysis provides insights into how pelagic fishing fleets and shark distributions interact that could inform management strategies to reduce bycatch.
This document discusses the successes and challenges of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) in managing marine resources in the Southern Ocean surrounding Antarctica. CCAMLR has successfully managed fisheries through an ecosystem approach, addressing issues like seabird bycatch and illegal fishing. However, it faces ongoing challenges around balancing conservation and fishing interests, and debates around climate change and establishing marine protected areas. CCAMLR's consensus-based decision making has helped shape outcomes but can be challenging with differing member interests.

The said seminar was attended by 75 participants held at the Goverrnor's Hall, Capitol Building, Bacolod City, Negros Occidental on 18-19 September 2013.
Marine pollution from fishing vessels is a serious problem in the Western and Central Pacific Ocean region. Analysis of over 10 years of pollution incident reports from observers on purse seine vessels found that the majority (71%) related to waste being dumped overboard, including 37% plastic waste. Limited data on longline vessels showed fewer reported incidents due to very low observer coverage levels. Increased monitoring and enforcement is needed for all vessel types, along with outreach programs and improved port waste facilities, to reduce ocean-based marine pollution in the region.
This document discusses efforts to improve coral reef health through increasing populations of herbivorous fish. It summarizes the mandate of the Specially Protected Areas and Wildlife (SPAW) Protocol of the Cartagena Convention to protect habitats and species in the Wider Caribbean Region. The SPAW Sub-Programme aims to increase protected areas, conserve threatened species, and facilitate information exchange to support biodiversity conservation. Specific efforts discussed include marine protected areas, action plans for marine mammals, invasive lionfish, sargassum seaweed, and fishing species like conch and lobber. The document also mentions work to evaluate the status of parrotfish and other herbivores that could potentially be listed under the SPA
This document discusses methodological support for exploring the properties of the Large Fish Indicator (LFI) for interpreting changes in the fish community of the South Adriatic Sea. It analyzes time series data from 1996-2003 using three size thresholds (20, 30, 40 cm) and two metrics (number of individuals, weight). The results show that a threshold of 30 cm accounts for a higher proportion of biomass compared to 40 cm, with lower variability than 20 cm. For both thresholds, hake is the most important species. Future steps proposed include expanding the analysis to other areas and exploring relationships between LFI and other indicators.
This document summarizes a study that developed habitat suitability models for four cephalopod species (Todaropsis eblanae, Illex coindetii, Eledone moschata, and Eledone cirrhosa) in the Strait of Sicily using data on species densities and environmental variables collected from 1998-2011. Generalized additive models were used to relate species presence/absence and abundance to depth, slope, rugosity, salinity, temperature, chlorophyll-a, and light levels. The models showed different habitat preferences between species that relate to environmental conditions. Predictive maps highlighted key habitat areas that can inform conservation efforts in the region. Further analysis of long-term trends is planned.

The document describes a workshop that evaluated management strategies for small pelagic fisheries using the BEMTOOL model. The model requires biological, fishery, economic and reference point data. Scenarios were developed to reduce fishing mortality to reach FMSY by 2020 through effort reduction. Model outputs included projections of stock biomass and landings against targets and forecasts of fleet economic indicators. Results showed that management scenarios improved stock status while reducing revenues compared to the status quo.
The document discusses expanding the scope of uncertainty in the BEMTOOL fisheries management model. It evaluates three approaches to incorporating process uncertainty in stock-recruitment relationships: 1) using parameters from a uniform distribution, 2) using parameters estimated by Eqsim, and 3) using parameters from normal distributions. It also discusses incorporating uncertainty in growth parameters, natural mortality, maturity, and selectivity to model process and parameter uncertainty. The goal is to make BEMTOOL forecasts more robust by fully representing uncertainty when evaluating management strategies.
BEMTOOL is an integrated bio-economic modeling platform developed by COISPA to simulate fisheries. It consists of 6 interlinked modules - biological, impact, economic, management, fleet behavior, and multi-criteria decision analysis. BEMTOOL can model multiple fish stocks and their interactions with several fishing fleets. It integrates uncertainty and propagates it through forecasts. BEMTOOL has been used in projects to evaluate management scenarios for fisheries in the Mediterranean and Black Seas.
The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

10. RAPPORTI CON LA POLITICA COMUNE PER LA
PESCA: COSA
Lo scopo principale della gestione della pesca nell’ambito della politica comune della pesca (PCP)
è garantire livelli di catture elevati a lungo termine per tutti gli stock entro il 2015, ed al più tardi
entro il 2020 (principio del rendimento massimo sostenibile - MSY).
11. RAPPORTI CON LA POLITICA COMUNE PER LA
PESCA: COME?
La gestione della pesca può assumere la forma di controllo dell’input o dell'output o una
combinazione di entrambi. Il controllo dell'input comprende:
§Norme sull'accesso alle acque per controllare chi pescherecci ha accesso a quali aree
§Controlli sullo sforzo di pesca per limitare la capacità di pesca e lo sforzo
§Misure tecniche per disciplinare l’uso delle attrezzature da pesca e i periodi di pesca

Abstract
Management of catches, effort and exploitation pattern are considered the most effective measures to control fishing
mortality and ultimately ensure productivity and sustainability of fisheries. Despite the growing concerns about the spatial
dimension of fisheries, the distribution of resources and fishing effort in space is seldom considered in assessment and
management processes. Here we propose SMART (Spatial MAnagement of demersal Resources for Trawl fisheries), a tool for
assessing bio-economic feedback in different management scenarios. SMART combines information from different tasks
gathered within the European Data Collection Framework on fisheries and is composed of: 1) spatial models of fishing
effort, environmental characteristics and distribution of demersal resources; 2) an Artificial Neural Network which captures
the relationships among these aspects in a spatially explicit way and uses them to predict resources abundances; 3) a
deterministic module which analyzes the size structure of catches and the associated revenues, according to different
spatially-based management scenarios. SMART is applied to demersal fishery in the Strait of Sicily, one of the most
productive fisheries of the Mediterranean Sea. Three of the main target species are used as proxies for the whole range
exploited by trawlers. After training, SMART is used to evaluate different management scenarios, including spatial closures,
using a simulation approach that mimics the recent exploitation patterns. Results evidence good model performance, with
a noteworthy coherence and reliability of outputs for the different components. Among others, the main finding is that a
partial improvement in resource conditions can be achieved by means of nursery closures, even if the overall fishing effort
in the area remains stable. Accordingly, a series of strategically designed areas of trawling closures could significantly
improve the resource conditions of demersal fisheries in the Strait of Sicily, also supporting sustainable economic returns for
fishermen if not applied simultaneously for different species.

At present, the assessment and management of Adriatic Sea fishery resources are based on data that do not fully
account for the complex spatial patterns arising from fleet behavior and/or species’ behavior and biology, mainly
because logbooks do not guarantee adequate coverage of the fishing activity exerted by the fleet. For data
collection, the Adriatic Sea is divided into two management areas (namely FAO Geographical Sub-Areas–GSAs).
To account for these spatial patterns while using the data available, we propose a method for estimating the
monthly landings of Italian trawlers operating in the Adriatic Sea at a higher spatial resolution than the GSA. We
use a stepwise approach based on the combined analysis of questionnaire-derived vessel-specific landings and
the spatial activity of the vessels with respect to a set of fishing grounds. Thus, we sequentially 1) analyze the
available vessel monitoring system data, 2) partition the study area into fishing grounds (the origin of the
landings), 3) cross analyze vessel-specific fishing efforts with the available vessel-specific monthly landings to
estimate the LPUE of each fishing ground, and 4) estimate the monthly landings (by vessel, fishing ground, and
harbor) for the whole fleet and the monthly fluxes between fishing grounds (origin) and landing harbors (the
destination of the landings). We apply the method to two species: the Norway lobster and the European hake. For
both species, we find a few fishing grounds to be consistently more productive than others and the landings per
harbor to vary greatly but with few harbors regularly receiving a significant share. In particular, the results
suggest that the Pomo/Jabuka pit area represents a critical area for both species. Additional outcomes include a
detailed characterization of the activity of the Adriatic bottom trawling fleet, highlighting the strengths and
shortcomings of the official data available. We discuss the results in the context of the current management
paradigm.
