A photograph taken over 150 years ago, originally intended to document British overseas military installations in Bermuda, is now a historical reference point helping scientists measure the impacts of local sea-level rise. Although the subjects of the photograph were the Commissioner’s House and various fortifications along the slip in the Royal Naval Dockyard, the image also captured a fixed biological phenomenon that can be used to interpret sea-level: a stable community of cyanobacteria that lives just above the high-water mark.

New research published in Nature has revealed the importance of mineral forms of iron in regulating the cycling of this bio-essential nutrient in the ocean.

This summer marks year two of a three-year ASU BIOS study designed to expand understanding of how ocean eddies might be affecting coral reefs, as well as what role eddies may have played in reef accretion and overall functioning in the past.

Now in its eighth year, BIOS-SCOPE is a multi-institutional, multi-disciplinary initiative that annually gathers scientists from Bermuda, Europe, the United Kingdom and the United States to explore fundamental questions about the ocean’s biogeochemical cycles and how diverse communities of marine microbes influence the carbon cycle and other fundamental processes and, ultimately, the planet’s ability to sustain life. An overarching goal of the project is to form and foster collaborations across scientific disciplines, an aspect that enables the team to advance their understanding of the interactions of organisms and compounds at various scales, across both time and ocean depths. Along the way, the principals and collaborators of BIOS-SCOPE (Bermuda Institute of Ocean Sciences – Simons Collaboration on Ocean Processes and Ecology) have formed professional bonds and friendships that add value to the work. On the eve of the program’s eleventh cruise from ASU BIOS – with 18 scientists and two marine science technicians on board, Currents spoke with BIOS-SCOPE Co-Principal Investigators and adjunct faculty Craig Carlson (University of California, Santa Barbara) and Stephen Giovannoni (Oregon State University) and Investigator Rachel Parsons (ASU BIOS Microbial Ecology Laboratory) about the project’s past, present and future.

A newly described coccolithophore species, Calciopappus curvus was recently found in 2020 in the Sargasso Sea near Bermuda by scientists affiliated with the Bermuda Institute of Ocean Sciences, a unit of the Julie Ann Wrigley Global Futures Laboratory at Arizona State University (ASU BIOS). This newly named species has also been observed prior to its discovery off Bermuda in water samples from far-flung locations as the North Atlantic to tropical and subtropical regions of the Mediterranean, the Atlantic, Indian, and Pacific Ocean.

Research conducted as part of the multi-year, multi-institutional BIOS-SCOPE (Bermuda Institute of Ocean Sciences – Simons Collaboration on Ocean Processes and Ecology) project is shedding light on how the end products of cellular metabolism, called metabolites, could be used to track future changes in the marine environment.

Over two days in mid-August, a team of BIOS scientists, along with the Institute’s science writer, supported the Bermuda Underwater Exploration Institute’s (BUEI’s) inaugural “Earth Reporters: Climate Change” summer camp. Designed for students aged 11 to 14, the week-long camp aimed to provide participants with the skills required to investigate environmental issues, then report on their findings using a variety of journalistic techniques, including photography, storytelling, and videography.

It’s rare that we hear about a new species discovered in Bermuda’s waters. Even rarer to hear about dozens of new species. And rarer still when these species play a key role in the global carbon cycle. A team of researchers led by Josué G. Millán, PhD candidate at Indiana State University and including BIOS zooplankton ecologist Leocadio Blanco-Bercial, have discovered 40 new morphospecies, and likely one new genus, of undescribed coccolithophores—a type of phytoplankton.

In early February, the Government of Bermuda released a public report titled “The State of Bermuda’s Marine Waters: A Snapshot of Bermuda’s Exclusive Economic Zone (EEZ) from the Coastline to 200 nautical miles (nm).” It was released as part of the Bermuda Ocean Prosperity Programme (BOPP), a partnership between the Government of Bermuda, the Waitt Institute, and BIOS designed to sustainably protect and manage the island’s ocean resources. BOPP is also working with the Government and local industries, such as tourism and fisheries, to diversify national revenue and support the development of a “blue economy” that balances the sustainable use of ocean resources with marine ecosystem health.

Climate change will challenge many of the processes that sustain life around the globe, but new research led by Bigelow Laboratory for Ocean Sciences provides a fresh look at the planet’s resiliency. The results reveal how microscopic ocean life that drives the carbon cycle in the Atlantic is adapting to warmer conditions. The news does not mean the end of the planet’s concerns, but it can help researchers better forecast the future.
