Smithsonian scientists become shark detectives to track species in the Chesapeake Bay

A shark rests in a holding tank on a Florida expedition. Before and after having their tags inserted, the sharks are kept in small pools for comfort and recovery. (Photo by Jay Fleming) When many people think of the Chesapeake Bay, one of the first creatures that comes to mind is the iconic blue crab. But parts of the bay are also home to several species of shark. Scientists have…

Some dolphins cross the Pacific more easily than others. Why that matters for protecting them.

These eastern spinner dolphins from the eastern Pacific are a unique subspecies and look very different from spinner dolphins in other parts of the world. New research led by Smithsonian researcher Dr. Matthew Leslie (conducted at Scripps Institution of Oceanography and NOAA’s Southwest Fisheries Science Center) compared global patterns of DNA in spinner dolphins and pantropical spotted dolphins.

MarineGEO survey conducted in Hong Kong

This MarineGEO settlement structure was submerged in Tung Ping Chau for two years. Many of these eight-level structures deployed in and around Hong Kong were found to have more than 300 visible organisms living in and on them. (Image courtesy The University of Hong Kong) Some of Hong Kong’s most disturbed and pristine marine environments were the recent focus of an intense 10-day MarineGEO survey of living organisms by a…

Earth’s oceans are losing their breath. Here’s the global scope

Low oxygen caused the death of these corals and others in Bocas del Toro, Panama. The dead crabs pictured also succumbed to the loss of dissolved oxygen. (Credit: Arcadio Castillo/Smithsonian) In the last 50 years, the amount of water in the open ocean with zero oxygen has increased more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than 10-fold since 1950. Scientists expect…

The Caribbean is stressed out

By measuring ocean health in the same way at sites across the Caribbean, it’s possible to understand where coastal environments are the most stressed out. “If people get their act together very soon, there is still hope of reversing some of these changes,” said Rachel Collin, director of the Bocas del Toro Research Station at the Smithsonian Tropical Research Institute, one of the participating marine-monitoring stations.

In San Francisco, one wet winter can switch up Bay’s invasive species

Richmond Marina, in northeastern San Francisco Bay, where the study was conducted. (Flickr photo by P9170033) For many Californians, last year’s wet winter triggered a case of whiplash. After five years of drought, rain from October 2016 to February 2017 broke more than a century of records thanks to a series of “Pineapple Express” storms, referring to atmospheric rivers that ferry moisture from Hawaii to the Pacific Coast. In San…
