Four video cameras look westward over the coast and the coral reef at Tres Palmas in Rincón, on the west coast of Puerto Rico. Two cameras look out at the horizon and over the ocean for the mid-field view; one camera offers a zoomed-in, far-field view overlooking the reef and out to the island of Desecheo, a U.S.

The SQUID-5 is an acronym for a Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with 5 cameras.

Two red sea urchins (Mesocentrotus franciscanus) sit on the deck of the R/V Falkor. These sea urchins were collected during the #HuntingBubbles research cruise led by the USGS and Schmidt Ocean Institute, which focused on exploring and understanding methane seeps and the communities that depend on them along the Cascadia Margin.

Marine geochemist Renee Takesue collects a sample of exposed mud in a marsh near Sonoma Creek, California. She will look here and in nearby San Pablo Bay for chemicals from the 2017 Nuns Wildfire that can harm wildlife. The stormy winter of 2018 may have transported these contaminants from the Sonoma Creek watershed into San Pablo Bay National Wildlife Refuge.
