Assessing the Impacts of Derelict Fishing Gear

Marine debris is a complicated global problem, but it is an important one that must be addressed to increase the sustainability of global fisheries. One of the most harmful types of marine debris is derelict fishing gear (lost or discarded), which threatens marine life and seafloor habitats like coral reefs since traps and nets can continue to catch fish and other marine life long after they have been discarded.

Argo Observations: A Key Component in Climate Change Research

Global warming refers to the gradual increase in the Earth's surface temperature that has been observed since the pre-industrial period (between1850 and 1900). This phenomenon is primarily caused by human activities, particularly the burning of fossil fuels, which increases the levels of greenhouse gases that trap heat in the Earth's atmosphere...

Long-Spined Sea Urchin: The Unsung Hero of Healthy Coral Reef Ecosystems

During the 1970s, if you swam, snorkeled, or dove in the Caribbean, it was common to find numerous reefs with colorful structures of various shapes. These structures, made of calcium carbonate, are nothing more than some of the longest-lived animals on our planet: corals. Some corals even began to form over 50 million years ago. The spectacular shades of color that we see when looking at a coral are...
