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.
Three-year study seeks to evaluate the potential of artificial upwelling and identify depth and intensity scenarios that mitigate coral bleaching effectively with minimal risk of unwanted side effects.
Even casual observers of environmental science understand the fundamental interconnection between atmospheric conditions and the well-being of marine ecosystems. What happens in the atmosphere inevitably finds its way into the ocean and, vice versa, the outcomes of deep ocean processes eventually bubble up to the surface and into the air above. Yet, the authors of a recently published paper point out, one would be hard-pressed to find these connections between the air and ocean represented adequately – if at all – in international environmental policies and regulations.
Samantha Hallam and ASU BIOS COO Mark Guishard are teaming up again to expand upon the work related to the effect of upper ocean heat on Bermuda hurricanes conducted during Hallam’s internship at BIOS in 2019.
A diverse and abundant group of single-celled marine organisms, Rhizaria are known to affect carbon and other chemical cycles of the world’s oceans, but specifics are lacking. Research has been hampered by difficulties sampling, culturing and preserving many types of this protist super-group, and they have been underrepresented in models of global geochemical cycling as a result. Researchers and partners from two U.S. universities are seeking to change that narrative through a new three-year National Science Foundation-funded study.
