Abstract:
El recientemente lanzado satélite Landsat-8 tiene el potencial de dramáticamente mejorar nuestra habilidad para la determinación de concentración de los tres principales agentes colorantes de aguas dulce y costeras (clorofila, sedimentos y materia orgánica disuelta coloreada) mediante imágenes satelitales. El primer paso es remover el efecto de la atmósfera, para lo cual se diseña un algoritmo que utiliza dos pixeles de la imagen con reflectancias estimadas. Finalmente, las concentraciones son determinadas mediante un algoritmo de optimización que utiliza una look-up table de reflectancias generadas por el modelo físico HydroLight. En esta ocasión presentaré los primeros resultados de esta investigación.

The International Ocean Colour Coordinating Group (IOCCG) was established in 1996 with the aim of developing consensus and synthesis on a global scale in the subject area of satellite ocean colour radiometry (OCR). It operates as an Affiliated Program of the Scientific Committee on Oceanic Research (SCOR) and comprises a rotating committee of representatives from each of the major international space agencies that provide ocean colour data, as well as representatives from the scientific community that use ocean colour data for research and applications. Space agencies contribute financially to the IOCCG and carry out the decisions endorsed by the group, while the scientific members address current research issues and make recommendations. Currently, IOCCG works towards ensuring Continuity and Consistency of the Ocean Colour Data Stream in the framework of the CEOS Ocean Colour virtual constellation. Within the OCR-VC framework, the International Network for Sensor Inter-comparison and Uncertainty Assessment for Ocean Color Radiometry (INSITU-OCR) initiative aims at integrating and rationalizing inter-agency efforts on satellite sensor inter-comparisons and uncertainty assessment for remote sensing products, with particular emphasis on requirements addressing the generation of ocean colour Essential Climate Variables (ECV) as proposed by the Global Climate Observing System (GCOS). Since 2013, IOCCG organises a bi-annual International Ocean Colour Science Meeting, where the global OCR community can gather and exchange with peers and space agency representatives. In parallel to these new initiatives, the IOCCG has a continuing capacity building and training activity, and continues to increase its record of monographs, based on the work of its working groups (currently 5 WG are active).

Describe and explain satellite remote sensing mission for monitoring.pdfalshaikhkhanzariarts
Describe and explain satellite remote sensing mission for monitoring water, carbon and global
climate change.
Solution
In recent years, the subjects of water, carbon, and global climate change
have attracted worldwide attention by scientists and the media. Climate
change, whether associated with human- induced or natural
variations, has and will continue to be important to policy makers and the
public. It is clear from reports such as that by the Intergovernmental Panelon Climate Change
(IPCC) [1] that
Earth observations play a critical role in providing information for assessment
and modeling. Improving these observations, better quality and newvariables, is a goal of most
national
and intergovernmental space agencies. Major initiatives are under waythat will result in benefits
to a broad
range of our global society. In the United States, a decadal study [2] was recently completed by
the
Committee on Earth Science and Applications of the US National Research
Council. The committee called for a commitment from the U.S. administration
to Earth observations to secure benefits for mankind. The report gives both
direction and a large boost to U.S. satellite programs as it recommended NOAA
to restore key observational capabilities of satellite missions and also that NASA
and NOAA launch 17 new satellite missions in the next 10 years. The study also
adds an additional focus to these missions: societal benefits.
Other countries have also been expanding their Earth observation programs
with numerous advanced concept satellite missions. Of particular relevance to
this issue are articles describing the
Earth observing programs of the
European Space Agency (ESA),
the Japanese Aerospace Exploration
Agency (JAXA), the China National
Space Administration (CNSA), the
Canadian Space Agency (CSA), and
the National Space Program Office
(NSPO) of Taiwan.
The ESA has a long history of
Earth observation from space that
began with meteorological missions
and has included a series of increasingly
sophisticated radars that have
provided valuable data about climate
and the changing environment. The
ESA’s current and future Earth observing
is under its Living Planet
Programme and includes the Earth
Explorer, meteorological, and Sentinel
missions.
JAXA has supported a wide range
of satellite-based instruments and
platforms that have and will provide
global Earth observations for water,
carbon, and climate. Of particular
note for the future is the commitment
to the Global Change Observation
Mission (GCOM) that will launch a
series of two types of satellites (water
and climate) to provide consistent and
continuous observations of key variables
over a 15-year period.
In addition to the United States,
ESA, and JAXA programs, there are
strong satellite-based Earth observing
programs in Canada, China, Argentina,
Taiwan, and Brazil.
In this Special Issue some of the
most significant recent and future Earth
observing satellites planned to monitor
water, carbon and global clima.
C4.06: Towards continental-scale operational ocean and coastal monitoring usi...Blue Planet Symposium
Regionally tuned algorithms that deliver remotely sensed marine water quality products from the MODIS/Aqua sensor have been developed and validated for the Great Barrier Reef (GBR). Through the eReefs partnership, these algorithms are being transferred from the research domain and being deployed operationally via the national meteorological agency. Furthermore they are being adapted to work with two other ocean colour satellite instruments, SeaWiFS and VIIRS/NPP to enable extension of the monitoring time series, both historically and into the future. The production infrastructure to manage contemporary data flows from the VIIRS sensor is similarly being extended. In parallel, the validated remote sensing products are being integrated into a hydrodynamic and bio-geochemical regional ocean model through data assimilation to provide a holistic suite of monitoring products for the GBR.
This work is being undertaken with the goal of expanding the monitoring to more of Australia's marine jurisdiction. While the remote sensing algorithms themselves are parameterised for the atmospheric and optical characteristics of the GBR region, they are inherently flexible and are progressively being applied and tested in other locations where suitable in situ data are available. The data processing system for the GBR already is nested within the national data production operated by the Integrated Marine Observing System.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

116. BohaiBay Oil Spill(by Chosunilbo) The sea area polluted in an oil spill in China's Bohai Bay was five times as large as Beijing previously announced. A probe conducted by the Chinese State Oceanic Administration found that some 4,240 sq.km of water, or seven times the size of Seoul, were polluted by oil leaks from the Peng Lai 19-3 oilfield in Bohai Bay, the daily Xin Jing Bao reported Wednesday.Beijing admitted the oil spill for the first time on July 5, a month after two oil leaks occurred at China's largest marine oilfield on June 4 and 17, saying only 840 sq.km were polluted. But the water quality of a 3,400 sq.km area nearby dropped from Grade 1 to Grade 3.China National Offshore Oil Corp. and ConocoPhillips, the joint operators of the oilfield, said the oil spill was quickly contained and cleaned up, but earlier this week Beijing admitted that oil continues to leak out.The Chinese government on Wednesday ordered the operators to suspend production until there is no more danger of further spills. Concern is increasing about the safety of seafood from the West Sea. The city of Yantai in Shandong Province near the ill-fated oilfield has set up an observation post on the coast to check for pollution.
