Residents of the San Francisco Bay region have long suspected that its waters might be contaminated with copper, particularly when the native fish populations in the north bay began declining two decades ago. Such declines can typically be attributed to changes in water temperature; however – in this case – such changes weren’t observed, leading some to believe that copper toxicity might be to blame. Adding to their suspicions is the fact that copper levels in the waters periodically exceed the U.S. EPA water quality guidelines.

Since October 1988, scientists have been sampling the deep ocean waters of the Sargasso Sea as part of the Bermuda Atlantic Time-series Study (BATS) project, with 2013 marking the program’s 25th year of continuous operation by BIOS.

In mid-February, the strong winds felt across the island almost wreaked havoc on a moored buoy that is part of the Bermuda Ocean Acidification and Coral Reef Investigation (BEACON) project at BIOS. Luckily, BIOS Research Technician Andrew Collins noticed the buoy at Hog Reef had broken loose from its primary fixed mooring line, setting in motion a coordinated effort to recover the buoy and its suite of scientific equipment.

In 2003 the field of Arctic research was significantly advanced by the signing of a Memorandum of Understanding (MOU) for World Ocean and Polar Regions Studies between NOAA and the Russian Academy of Sciences. This groundbreaking agreement paved the way for a new level of collaboration between these two countries in their ongoing efforts to understand the dynamics of the Arctic sea region. The Russian-American Long-term Census of the Arctic (RUSALCA) program was the first research program initiated under this MOU, aimed at studying the ocean carbon cycle and the impacts of ocean acidification on the marine environment in the rapidly changing Arctic Ocean.

Amid growing concern regarding the current federal funding climate for ocean science research, the National Science Foundation (NSF) just announced continued support for the Bermuda Atlantic Time-series Study (BATS) research program at BIOS. According to Dr. Nicholas Bates, Senior Scientist and Associate Director of Research at BIOS and Principal Investigator of the BATS project, “This represents about $14 million from NSF to BIOS over the next five years: approximately $6 million for research and roughly another $8 million to support science days at sea aboard the R/V Atlantic Explorer.” This announcement comes on the heels of a $4 million award from NSF last year to support Hydrostation S, the world’s longest-running hydrographic time-series, for another five years. Together, these two awards represent a significant commitment by NSF to ocean time-series off Bermuda.

From October 18-25, 2013, a group of scientists and technicians were at sea aboard the R/V Atlantic Explorer on a very special Bermuda Atlantic Time-series Study (BATS) research cruise marking the program’s 25th year. Like many anniversary celebrations, this one involved cake (more on that in a bit!) but—unlike most celebrations—it also involved a variety of oceanographic science.

In the late 1980s Rod Johnson was working in the UK civil service—a “fantastic job” by his own account—when he attended a meeting concerning the Global Ocean Flux Study (GOFS). During this meeting a topic of discussion was how Bermuda and Hawaii would be pivotal in achieving the GOFS objectives of understanding biogeochemical variability in the oceans and the impact of climate change on these processes.  At the time, Johnson’s girlfriend (Sarah), now his wife, had just moved to Bermuda and, in a move that would impact the course of his career, he decided to contact Dr. Tony Knap, then-Director of BIOS (at the time BBS), to inquire about employment opportunities.

In the late 1980s scientists at the Bermuda Institute of Ocean Sciences (BIOS) were looking for a way to meaningfully contribute to the Joint Global Ocean Flux Study (JGOFS). This international program involved the creation and maintenance of monitoring stations around the world, each collecting vast amounts of data on dissolved carbon in the ocean and carbon dioxide in the atmosphere. BIOS was already home to Hydrostation S (an ocean data time-series station established in 1954), but the scientists envisioned a time-series station that could provide long-term measurements from the open ocean off Bermuda.

BIOS oceanographer Rod Johnson is the chief scientist on board a cruise this month offshore Bermuda using a new underwater vehicle designed to reduce costs and improve science efficiency at sea, while gathering samples for biological and chemical analyses from the ocean water column.

Funds granted in May by the National Science Foundation will allow BIOS scientists to continue their research through 2023 at the Bermuda Atlantic Time-series Study (BATS) site, a project established in 1988 by BIOS and collaborators to examine the “time-varying” components of the ocean carbon cycle, ocean physics, and biology.
