Stormy Seas at Oil Spill Ground Zero

In today's update from the boat, Will Race describes the crew's arrival at oil spill ground zero to deploy oil measuring straps. As you can see from today's photos, the crew endured the roughest conditions on the expeditions yet:

The site of the Deepwater Horizon was the focus of the day. The objective was to establish a 10 kilometer diameter of moorings around Deepwater Horizon site. With an average water depth of 1600 meters, the Oceana team knew it would be a long day.

At 6:30am team members positioned themselves on deck and had the pleasure of witnessing a beautiful Gulf of Mexico sunrise. Amidst the landscape of sunny cumulous clouds and dark unwieldy thunder fronts, there sat the site of the Deepwater Horizon. It was very noticeable thanks to the small city that has been crafted around the site. Shadows loomed over the spill site and brought a sobering reminder to what the objective of the day was.

Mapping the Oil Plume

On Friday the Latitude set off on the next leg of the journey: measuring the underwater oil plume in the Gulf of Mexico. Here’s our on-board dispatcher for this leg, Will Race, on the very wet start to the experiment:

On Friday, the crew held a strategy meeting to discuss the next seven days and what’s in store. Pacific Science Director Dr. Jeff Short explained his science experiment: The basic approach for evaluating the subsurface oil plumes will be the deployment of an array of moorings with sensor strips every 100 meters.

Moorings will be deployed in three main areas: 12 within 5 km of the wellhead, 12 in a rectangular array extending up to 90 km to the northeast of the wellhead, and 12 in another rectangular array extending up to 90 km southwest of the wellhead.

With everyone in agreement, it was time to go. Due to the drastically shallow shore line, the Mississippi Port Authorities require a local captain come aboard to navigate boats through the shallows, until they are offshore. An additional treat was when pelicans and various other marine birds decided to escort us out to sea.

Once out at sea, the Oceana team continued to assemble gear for the next day’s first mooring drop. We traveled nearly 10 hours to the first drop site.

While Oceana’s senior campaign communications manager Dustin Cranor gets a much-deserved break on land, Pacific administrative assistant Will Race will be sending us updates from the boat for the next few weeks. Here’s Will's first post:

Wednesday brought heat, humidity and eight new Oceana staff members, who will take part in a two-week oil plume experiment. Alongside Vice President of Oceana Europe, Xavier Pastor, the experiment will be led by Pacific Director, Susan Murray and Pacific Science Director, Dr. Jeff Short. The team will head out Friday to begin the study.

The Oceana Latitude also had to say goodbye to ROV operator Matthias Gorny and Oceana Pacific office staff Cayleigh Allen. The two embarked on a three day journey to Monterey, California, where they will participate in the Oceana Pacific California Current expedition and use the ROV to document important ecological areas of Monterey Bay.
