Here's a glimpse of what our group has been working on this week. The video is part of our presentation, so there's no sound. But in short, we've been mapping out kelp growth around Catalina Island and analyzing threats to the kelp population. Special thanks to the USC Wrigley Institute for Environmental Studies for all of the resources they provided us.
Since the first grant that included funding for use of a Wave Glider back in 2010, researchers have received grants for Wave Gliders to collect climate change data, sample chlorophyll blooms, monitor marine life, explore polar seas, and more. See several examples of work that inspires us.

ABSTRACT- The present investigation on the impact of fungicides on the growth and development of Spodoptera litura
was carried out in the laboratory of the Department of Entomology, SKUAST- Jammu, during the year 2012-13. Base-line
toxicity of two fungicides viz., mancozeb and ridomil MZ were evaluated against S. litura in the laboratory. The results
showed that fungicides significantly influenced the growth and development of S. litura. The larval development duration
was significantly short, and it was an average (14.61± 0.30), (16.28±0.66) days, when treated with ridomil, and mancozeb
respectively. The results show that fungicides can serve a practical tool to reduce the S.litura and may assume a greater
role in integrated programs showed to manage insect pests and pathogens.
Key-words- Spodoptera litura, Fungicides, Bioassay, Growth and development

Role of control and instrumentation in thermal power plant.
Use of various instruments for the measurements of flow, pressure and temperature in industries.
The immense region of the world’s seas has long enraptured human interest, filling in as both a wellspring of secret and a boondocks for logical investigation. Throughout the long term, propels in sea life science have unfurled like the pages of a convincing story, uncovering the complexities of maritime environments, the elements of marine life, and the significant impact of the seas on Earth’s environment. From the beginning of sea investigation to the present state of the art advancements, the excursion of understanding our seas has been set apart by constant development and disclosure.
This gathering plans to diagram the momentous advances in sea life science, giving a thorough outline of the developing scene of maritime exploration. We will investigate the pivotal moments, revolutionary technologies, and collaborative efforts that have shaped our understanding of the oceans as we delve into the depths of this multidisciplinary field. From the revelation of aqueous vents and the planning of sea flows to the investigation of outrageous remote ocean conditions, every part in this investigation of sea life science mirrors the vigorous quest for information that drives researchers, specialists, and pioneers the same.
The job of sea life science reaches out past the domains of unadulterated interest. It assumes a critical part in tending to squeezing worldwide difficulties, for example, environmental change, overfishing, and the protection of biodiversity. As we face a period of exceptional ecological change, the bits of knowledge acquired from sea life science become progressively crucial for educated independent direction and supportable administration regarding our seas.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
WRI’s brand new “Food Service Playbook for Promoting Sustainable Food Choices” gives food service operators the very latest strategies for creating dining environments that empower consumers to choose sustainable, plant-rich dishes. This research builds off our first guide for food service, now with industry experience and insights from nearly 350 academic trials.
