Fishing line wrapped on strut between hulls of Western Flyer

Divers remove line caught on Western Flyer

On March 17, MBARI's research vessel Western Flyer returned to the dock in La Paz after a two-week midwater-biology cruise. While the ship was at the dock, researcher Steve Haddock and ROV Pilot Randy Prickett dove underneath the boat to clear a line that had become wrapped around part of the boat. The ROV pilots spotted the offending line during an ROV launch when visibility was particularly good. Earlier in the Gulf of California expedition, MBARI's mapping AUV became tangled in a fishing line 450 meters (almost 1,500 feet) below the surface.

Johnny with ship's propeller

Recycled propeller installed at MBARI front entrance

MBARI has a new art piece in front of its main entrance—an old propeller from one of its research vessels, the Rachel Carson. The bronze propeller is five feet across and weighs 1,000 pounds; a crane was required to install it in place. The R/V Rachel Carson originally operated as an oil field supply vessel in the Gulf of Mexico. MBARI purchased the ship in July 2011 and transited it from La Rose, Louisiana, to Alameda, California, for extensive refitting at the shipyard. The propeller was removed during the refit.

pH meters in test tank

MBARI engineers compete in third phase of XPRIZE competition

Last fall, MBARI hosted the first two phases of the Wendy Schmidt Ocean Health XPRIZE competition. The competition challenged teams to design robust pH sensors that could accurately and affordably measure ocean acidification. Eighteen teams participated in the first phase of the competition; 14 teams made it to phase three. The third phase took place earlier this month, when instruments that survived the first two phases were tested in challenging coastal conditions in Seattle, Washington. The instruments were placed in a test tank built near the Seattle Aquarium, with continuously pumped seawater from Puget Sound. The purpose of this phase was to test the instruments’ resistance to biofouling. Ken Johnson, a senior scientist at MBARI, and Hans Jannasch, a senior research specialist, are members of Team DuraFET, one of the teams that participated in the phase-three testing.

FOCE in Antarctica

Ocean acidification studies in Antarctica

Ocean acidification poses a threat to the life and diversity of marine ecosystems. MBARI scientists and engineers have designed a sophisticated tool for studying the effects of ocean acidification that can be applied to various marine environments, from shallow-water kelp forests to the deep sea. This tool, called the Free Ocean Carbon Enrichment (FOCE) system, allows researchers to study the impacts of ocean acidification on marine animals in their natural habitat. The system is available as an open-source package to researchers wanting to use FOCE technology in marine environments of interest. The FOCE system developers at MBARI help researchers install systems in these environments. Outside of Monterey Bay, the FOCE system has been installed in the bay of Villefranche-sur-mer (France) and Heron Island, on the Great Barrier Reef. Recently, John Stark and Glenn Johnstone, of the Australian Antarctic Division of the Department of the Environment, sent word from Antarctica that their system (called antFOCE) was installed successfully and is functioning properly.
