EARS: hearing and recording marine mammal sounds

Heavy lifting: Notes from the field Sean Griffin, EARS team leader. “June 22-23, 2015: The EARS team started the “ship load out” (loading gear onto the ship) in port early Monday and finished on Tuesday long after the R/V Pelican left port. Like all load-outs, this one involved a lot of heavy lifting and squeezing […]

Glider “Otis” reports for duty

The first three days of flight: Notes from the field Stephen Pierce, glider pilot. June 24, 2105. Noon.  “SG608 (Otis) has been deployed and completed a short dive. I am now sending it down to about 200 meters; ease its way deeper while trimming over the rest of today. All looks good so far.  Might […]

Into the Gulf of Mexico

Days Two and Three: Notes from the field Douglas Dougas, cruise photographer June 23, 2105. “We left at 3:35pm CST. Departure went smoothly. The weather at LUMCON was very hot and humid and extremely challenging to work in- the EARS crew had sweat dripping from their faces as they prepared equipment on the deck during […]

Here we Go! The 2015 cruise gets underway

Day One: LUMCON Cocodrie, Lousianna For any research cruise, Day One is all about the ‘business end’ of a field operation. Much has to happen before departing from Cocodrie, LA, home port for the R/V Pelican (provided by LUMCON-The Louisiana Universities Marine Consortium). Because, once out in the Gulf, time is definitely money and turning […]

Rare Sperm Whale Encounter with ROV Hercules In the Gulf of Mexico April 2015

Rare Sperm Whale Encounter with ROV Hercules In the Gulf of Mexico April 2015

Sperm whales are a target species for LADC:GEMM.  At 598 meters (1,962 ft) below the Gulf of Mexico off the coast of Louisiana, the ROV Hercules (Ocean Exploration Trust) encountered a massive sperm whale. It circled Hercules several times, giving the cameras a chance to capture incredible footage. Encounters between sperm whales and remotely operated […]

Ocean Gliders

Ocean Gliders

We will be using ocean gliders that will have  hydrophones attached to record sounds in the environment while they ‘fly’ through the water on a pre-set tracks. We can locate and identify different whale and dolphin species with this technique, and determine their abundance from the acoustic data.  We will be launching our gliders for […]

Autonomous Surface Vehicles

Autonomous Surface Vehicles

ASVs can be though of as ‘sailboats’. They can be programmed to cruise a specific route and at a specific speed. We can record ocean sounds and collect other environmental data from these platforms.  Our first launch for our up-coming research will be in the summer of 2015.  Stay tuned for many updates!
