From the Deep Sea to Deep Space: Sea Urchin’s Teeth Inspire New Design for Space Exploration Device

20160405-Sea-Urchin-Robot-8560-ok.jpg

The sea urchin’s intricate mouth and teeth are the model for a claw-like device developed by a team of engineers and marine biologists at the University of California, San Diego to sample sediments on other planets, such as Mars. The researchers detail their work in a recent issue of the Journal of Visualized Experiments.

New Study Found Ocean Acidification May Be Impacting Coral Reefs in the Florida Keys

In a new study, University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers found that the limestone that forms the foundation of coral reefs along the Florida Reef Tract is dissolving during the fall and winter months on many reefs in the Florida Keys. The research showed that the upper Florida Keys were the most impacted by the annual loss of reef.

Mother Nature Overshadows Impact of Anglers

When it comes to reducing the number of walleye, anglers take a back seat to Mother Nature. That’s the one of the insights on harvest dynamics emerging from a research project to assess movement, mortality and the impact of anglers on walleye populations along the Missouri River from the Oahe Dam near Pierre, South Dakota, north to the Garrison Dam near Riverdale, North Dakota.

A drop in the amount of oxygen dissolved in the oceans due to climate change is already discernible in some parts of the world and should be evident across large parts of the ocean between 2030 and 2040, according to a new study.

Cutting-Edge Telepresence Technology Helped Investigators Find the El Faro "Black Box"

Federal investigators found the “black box’’ that could reveal why the El Faro cargo ship sank off the Bahamas in a hurricane last fall. The University of Rhode Island played a key role in the discovery. URI’s acclaimed Inner Space Center at the Graduate School of Oceanography provided telepresence technology—and its expertise—to assist with the search.

Do Fish Survive in Streams in Winter?

113991_web.jpg

Most stream-resident fish stay throughout winter despite the ice. This has been shown by Christine Weber, previous researcher at Umeå University, by tagging trout and sculpins with transponders to follow fish migration. Fish's general state of health is the single most important factor for surviving winter. The findings have been published in the journal Ecology and Evolution.

Capturing Public Support for an Endangered Species Through Photography

Just four hours south of the UC San Diego campus lives the most endangered marine mammal in the world: the vaquita porpoise. Despite the Mexican government’s ban on gillnet fishing in the northern Gulf of California, fishermen on the hunt for totoaba fish and shrimp continue to use the nets illegally, leading to the incidental capture of vaquita, which become tangled in the nets and drown. According to the World Wildlife Fund, the estimated 100 individuals remaining are at risk of becoming extinct by 2018 if incidental capture is not prevented immediately.

Plastic Below the Surface

Current measurement methods may be vastly underestimating the amount of plastic in the oceans. Due to ocean's movement, trash may be well below the surface, making it difficult to adequately measure and remove.
