Monitoring sound in the Salish Sea: how scientists are trying to understand the decline of Southern Resident Killer Whales

Deployment of the hydrophone mooring.

The Salish Sea, located on the west coast of Canada, is bounded by the lower mainland of British Columbia to the east, Vancouver Island to the west, and the state of Washington to the south. This Sea is a bustling location, with millions of people living along its shoreline and numerous vessels sailing through its waters daily. It is also … Read More

FjordPhyto: Citizen science in the Antarctic

Oceanographers on a boat in the arctic.

Air and ocean temperatures have notably increased in the Antarctic since the 1950s, with publications finding that it is the third fastest warming region on Earth and that 87% of its glaciers are in retreat. Its nearshore, fjord-dominated areas are particularly sensitive to this glacial retreat, the effects of which can be detected throughout this crucial ecosystem where local megafauna … Read More

Resolving spatial and temporal variations in estuarine gas flux

Estuarine Gas Exchange Maximum (EGM) model

Estuaries are thought to be major players in the global carbon budget, acting as significant sources of carbon dioxide to the atmosphere. However, the uncertainties on existing measurements are high. A recent study led by Dr. Malcolm Scully, a researcher at the Woods Hole Oceanographic Institution (WHOI), aims to improve our understanding of global fluxes of CO2 from estuaries by examining how … Read More

Uncovering the Ocean Dynamics Off the Coast of Madeira Island, Portugal

RBRconcerto³ CTD mounted to a Del Mar Oceanographic (DMO) Wirewalker

In the lee of Madeira Island, a famous-to-oceanographers formation occurs. To better understand ‘Madeira-Mode Water’, a team of researchers from the Oceanic Observatory of Madeira (OOM) set out in July, 2018, with an RBRconcerto³ CTD mounted to a Del Mar Oceanographic (DMO) Wirewalker and observed the daily thermocline cycle at a new level of detail. From the Portuguese naval ship … Read More
