I am excited to be participating in WHOI’s GOMTOX project again this October. I will be sailing aboard a ‘Cyst cruise’, investigating A. fundyense, a toxic dinoflagellate (and one of the causative organisms of ‘red tide’ in shellfish) in the Gulf of Maine, Cape Cod, and Georges Bank. We will be looking to both monitor and predict ‘red tide’ and toxicity in shellfish beds, benthic sediments, and the water column.


Like snow sliding off a roof on a sunny day, the Greenland Ice Sheet may be sliding faster into the ocean due to massive releases of meltwater from surface lakes, according to a new study by the University of Colorado Boulder-based Cooperative Institute for Research in Environmental Sciences.

"Aerial of Scripps Pier taken from 450 meters (1,500 feet) during a Tetraselmis sp. bloom. This green flagellate is roughly 10 micrometers in size, and has been found in concentrations as dense as 15 million cells per liter of seawater. The foam became more prevalent at the end of July, though it has been observed off and on since the first week of July. Its patchy distribution makes it visible only at some beaches and the foam becomes more apparent in the afternoon when the wind and waves mix the surface waters. Tetraselmis has bloomed each summer since 2009 with blooms lasting from one week to several months. There are no documented health hazards with swimming or fishing in areas of Tetraselmis blooms."
