Mission Blue in the Gulf of Mexico: ocean exploration is no walk in the park

The ocean is an incredible laboratory for studying the complex intricacies of life itself. From the sea all life first came, so what better to place to learn. But it's not exactly a controlled environment where men and women in starched white lab coats can measure, test, and analyze in sterile, secure labs. No, out in the elements, it can be a challenging place where not all goes according to plan.

Dr. Sylvia Earle's Mission Blue organization knows this first hand as they have been attempting to study the after effects of the 2010 Gulf Oil Spill. It has been an expedition of successes and frustrations, but that is nothing new to anyone who has spent time on the seas.

There are many unanswered questions regarding the Gulf Oil Spill. Where has all of the millions of gallons of oil settled? Dissipated, evaporated, or consumed by bacteria and other microorganisms? Has it settled into the deep sea floor and is this having an impact on the many small bottom-dwelling forms of sealife that make an important foundation in the marine ecology. What of the many fish, like whale sharks and bluefin tuna, that migrate through the Gulf or use it as a primary breeding ground? Has there been an impact on them or their eggs or other larvae?

The list goes on and on.

"Speaking as a scientist," said Mission Blue researcher Eric Hoffmayer, "this oil spill in the Gulf of Mexico sort of caught us off guard. We don't know a lot about many of these animals. Whether it's whale sharks, tiger sharks, makos, whatever, we don't know what their habitat use is in the region. We don't have the baseline data. Without understanding how they use this environment, we don't know how the spill will affect them."

Ups and Downs

The Mission Blue expedition, supported by National Geographic, the Waitt Institute, and Dr. Earle's Hope Spots LLC, has been in the Gulf several times over the past few months. It has had great success in tracking down whale sharks that have been known to congregate in an area named Ewing Bank, off of Louisiana. This location is in relatively close proximity to the site of the spill. By tagging and tracking the sharks, in addition to studying the condition of the food sources that the sharks are living on as they pass through the area, researchers hope to gain some insight as to whether the oil has had an adverse impact on these huge filter feeders.

Mission Blue's latest expedition to the Gulf was planned as an opportunity to study marine life on the deep seafloor using the advanced ROV, Medusa, and travel throughout the water column, assessing the health of the openwater community using the two-man submersible, Deepworker. While the Medusa had several successful initial dives, using its red-lit video camera systems (red light, which fades quickly with depth, is less disturbing to deep water marine life as they are less sensitive to it), later dives were scrubbed due to rough seas.

Those wind-whipped seas continued to play havoc with a series of planned dives using the Deepworker submersible. A few dives were completed in shallow water, where Dr. Earle and Harte Research Institute director Larry McKinney had to contend with poor visibility - lots of phytoplankton to see up close but "big picture" views of the surrounding open water seascape were limited at best. As the expedition is drawing to a close, famed author and ecologist Dr. Carl Safina came aboard to share his experiences, having spent considerable time in the Gulf during the spill, and to hopefully get some dives in himself.



Perseverance in the face of challenging conditions is a fundamental requirement of ocean exploration. And if we are to understand the full ramifications of our actions on complex marine ecosystems with regards to oil drilling at sea, expeditions like that being undertaken by Mission Blue and other organizations will endure what nature throws their way and they will continue. The answers to so many questions must be found before we find ourselves faced with another environmental disaster; the result of our own ignorance.

G-20 Summit: Mission Blue, TED, and Oceana take on overfishing

After the disastrous March CITES conference, where conservation groups made heartfelt arguments for protecting tuna, sharks, and other critically important marine species - only to have well-oiled political machines representing commercial interests successfully block all proposals for protection - another opportunity for sensible conservation is presenting itself in June.

The G-20 Summit will be held in Toronto, Canada and several major conservation and think tank groups are working together to make up for lost ground. The Mission Blue project, a arm of the Sylvia Earle Foundation and supported by TED (Technology, Entertainment, and Design) - an innovation think tank - will be focusing on the government subsidizing of commercial fisheries and how that has exacerbated overfishing. With government support, commercial fisheries have pushed themselves into overcapacity, propping up an industry that is no longer economically feasible by perpetuating overfishing in a vicious cycle.

According to a press release from Oceana, who is also working with Mission Blue in preparation for the conference:


“'We believe that the G-20 nations have a powerful opportunity this summer to halt the practice of fishing subsidies and put the world’s fisheries back on a path to recovery and towards an abundant future,' said Chris Anderson, TED curator. 'Nearly all of the world’s fisheries are in jeopardy from overfishing and could be beyond recovery within decades if current trends continue.'

Despite international consensus on the dire state of the oceans, many governments continue to provide major subsidies to their fishing sectors. These subsidies promote overfishing by pushing fleets to fish longer, harder and farther away than would otherwise be economically feasible. The fleets are overcapacity – as much as 2.5 times what is needed to fish at sustainable levels. Destructive fisheries subsidies are estimated to be at least $20 billion annually, an amount equal to approximately 25 percent of the value of the world catch.

'Governments are paying companies to overfish our oceans,' said Andrew Sharpless, chief executive officer of Oceana and Mission Blue participant. 'It’s taxpayer-financed ocean depletion and it’s crazy. Cutting government subsidies that produce overcapacity in the world’s fishing fleets is the silver bullet to restoring our world’s fisheries.'"

You can learn more about Mission Blue at their web site and Facebook page. TED is a fascinating organization with conferences and online videos that cover a plethora of subjects. And of course, Oceana is one of the leading ocean conservation organizations.

The G-20 Summit in late June - another opportunity to get policy makers attuned to the reality of many threats facing our oceans and the urgency needed to address them.

Misson Blue: new web site from the Sylvia Earle Foundation

A new web site was launched yesterday that I highly recommend you take a look at: Mission Blue. This new site is part of Dr. Sylvia Earle's foundation and provides a sharp focus on many of her recent expeditionary activities, including an ongoing expedition and ocean conference at the Galapagos Islands.

Ocean conservation can be a very broad and overwhelming issue to get one's arms around, so many organization devote their resources and energy to more specific topics of interest. Mission
Blue accomplishes this by identifying Hope Spots - geographical marine areas of critical importance that can also serve to highlight specific marine issues or challenges. The web site allows you to select and learn more about a specific Hope Spot - ranging from the Seychelles off of Africa, to Antarctica's Ross Sea, to the Gulf of California (Sea of Cortez), and more.

There is a lot of great interactivity with the site, added by Dr. Earle's working relationship with Google, which provided map imagery and a handy version of Google Earth incorporated into the site. And then to round it off, there is a blog to keep readers updated with the activities of each expedition and other events with which Dr. Earle has been involved, such as the creative think tank organization, TED (technology, entertainment, design).

Mission Blue, another avenue for ocean conservation and enlightenment. Check it out.
