Person: Salvador Jorgensen

Dr. Salvador Jorgensen is a marine ecologist and holds the position of Senior Research Scientist in the Conservation Research department at the Monterey Bay Aquarium.  Jorgensen’s research focuses on the ecology, migration and population dynamics of pelagic fishes and elasmobranchs. His recent interests lie in understanding the distribution, abundance, and movement of ocean species and … Continued

Log Post: Behind the MicrobeEddyBots

The ocean is full of relatively small events that happen over a short period of time. To help scientists maintain a more persistent observing presence in the ocean, we use robots called Autonomous Underwater Vehicles (AUVs) to move around the ocean in three dimensions and collect data. On this research cruise we are using 3 … Continued

Log Post: The ‘Bots are Back! ~ Week 2 Video

Drama and suspense are not generally the first things people think of when oceanic research is discussed, but second week of the #MicrobeEddyBots research cruise provided plenty of both (spoiler alert: there is a positive ending). Check out this week’s video for insight into what researchers seek to discover using Autonomous Underwater Vehicles (AUVs), the obstacles … Continued

Log Post: Underway CTD’s – The Struggle is ‘Reel’

Although our expensive new robots can cruise underwater for days at a time, setting them up for their most scientifically valuable missions begins with compiling data to form a picture of the oceanic feature we are trying to study. Satellite altimetry shows us differences of tens of centimeters above or below the average sea surface … Continued

Log Post: Sampling Eddies

Nearly two weeks into the expedition, our cruise has achieved a number of impressive successes already: chasing the eddy, characterizing it, and tracking its features. The next challenge is an engineering one – sampling the eddy’s deep chlorophyll maximum (DCM) in real-time at a depth of ~100 meters, more than twice the depth recommended for … Continued

Log Post: Tracking Eddies

Once the LRAUVs Opah and Aku rendezvoused with the Falkor in the center of the eddy, it was time to switch them from survey mode to tracking and sampling mode. Our target eddy feature, the Deep Chlorophyll Max (DCM, discussed here), is indicated as a bright red/orange color in the data visualizations of Opah’s sensor … Continued
