Warmer, saltier, more acidic oceans threaten human, environmental health

The exhibit explores the exquisite beauty of plankton and its crucial role not only in ocean ecosystems, but in how ocean health is critical to our survival and elemental to all life on our planet.

Located southeast of Bermuda, Hydrostation ‘S’—a set of unmarked geographic coordinates (32 degrees 10 minutes North, 64 degrees 30 minutes West)—has yielded measurements of temperature, dissolved oxygen, salinity and other parameters every two weeks for seven decades.

Typically associated with the study of Earth’s upper atmosphere and beyond, satellites deployed by the National Aeronautics and Space Administration (NASA) also augment our understanding of Earth’s ecosystems, including critical information about the ocean such as locations of algal blooms and levels of marine photosynthesis.

Oceans are constantly changing. These changes don’t only affect marine life but also have wide-reaching consequences for land dwellers. To document them, monitoring stations in the North Atlantic Ocean have been active for decades. Now, researchers have reported on the latest changes, showing that compared to 40 years ago, the ocean near the island of Bermuda is warmer, saltier, more acidic, and has lost oxygen. Long-term monitoring can provide information about existential challenges societies will face in the near future, the researchers said.

Arizona State University launched four new ocean-focused degree programs within the College of Global Futures — a Bachelor of Science in ocean futures, a Bachelor of Science in ocean futures with a concentration in coastal and marine sciences, an online Master of Science in coastal and marine science and management, and a PhD in ocean futures.

$100 million vessel to be delivered to GSO in 2021

Richard Smith, In Memoriam – remembering ‘Chief’

BIOS marine superintendent and ship captain Quentin Lewis is calling the months ahead for the Institute’s research vessel the Atlantic Explorer “very healthy in terms of operating days.” At the start of 2021, BIOS has 195 days at sea funded for science programs, he said.

For more than a quarter century, the Bermuda Atlantic Time-series Study (BATS) has been making physical, biological, and chemical oceanographic measurements in the open ocean off Bermuda. Once or twice each month, researchers and technicians board the research vessel Atlantic Explorer and head 50 miles (82 kilometers) southeast of Bermuda to an area in the Sargasso Sea, where they collect valuable data on water column properties (including temperature, dissolved oxygen, and salinity) as well as bacterial production, zooplankton distribution, and abundance. Their data also shed light on the transport and cycling of organic carbon, phosphorus, and nitrogen.
