“I love diving with makos, but they have a very different behavior than other sharks. They come in appearing to be more agitated. They’re much more hyper and jacked up.” - Brian Skerry

Mako sharks are built to move. They are very acrobatic – sometimes leaping high into the air –and are also extremely fast. Some scientists think they are the fastest fish, possibly going over 50 mph at times. (Fun fact – makos are one of the only “warm-blooded” fish, which helps explain why they can move so fast, even in colder water.) Makos need wide open spaces and healthy places to eat and reproduce. The health of our oceans depends on healthy top predator populations, and healthy top predators depend on healthy oceans.

Our nation has taken a major step forward in protecting the health of our oceans with the National Ocean Policy – which calls better management through agency coordination, science-based decisions and robust public and stakeholder involvement.  One important priority of the National Ocean Policy is to protect ocean habitat and wildlife while supporting sustainable new and traditional uses of our ocean.

Regional ocean planning and ecosystem-based management are two other key components of the National Ocean Policy that can go a long way in protecting our top predators. Regional ocean planning is a process that brings together all our ocean stakeholders – from fishermen to whale watchers, from beachgoers to renewable energy developers – to help us figure out how to share the ocean sustainably. This process helps all New Englanders use and enjoy our ocean and coasts while making sure we protect ocean wildlife and habitats and maintain the benefits these resources provide for us all.

For an example of how regional ocean planning can protect marine wildlife, check out this blog about endangered North Atlantic right whales and shipping lanes.

Collecting and sharing good data, and using it to help make ocean management decisions, are some of the keys to succesful regional ocean planning. If you are wondering how this might apply to mako sharks, check out this app from NOAA that allows fishermen to share information about caught and released makos – to literally put that shark on the map. NOAA says “Overfishing is occurring on the North Atlantic shortfin mako shark population. By releasing shortfin mako sharks that are unintentionally caught or caught for sport, fishermen can lead the way for conserving this shark species.” Now that sounds like some good planning.

“I didn’t expect anything like this. Stalks of kelp that were 8 feet high and long strands at the top that made this golden bed… This is clearly a unique habitat.”

Success! After two prior attempts foiled by bad weather and rough seas, last weekend Brian Skerry at last reached Cashes Ledge and was able to explore this extraordinary, ecologically important seascape – a first for the peripatetic Skerry. For two days Brian and his crew swam in Cashes’ unearthly kelp forests, among its waving amber fronds and remarkable red cod, making pictures that will reveal the mysteries and beauty of this unique New England treasure so far unknown to most.

About 80 miles off the coast of Massachusetts, Cashes Ledge is a submerged mountain range that nearly pierces the surface of the ocean and is home to the deepest kelp forest in the North Atlantic. Fields of anemones and brightly-colored sponges produce a fascinating marine landscape surrounding Ammen Rock, the highest peak of Cashes Ledge and New England’s underwater equivalent of Mount Washington.

Cashes Ledge is important not only to marine organisms but also to people hoping to learn about the history of New England’s oceans – many scientists believe that Cashes Ledge represents the best remaining example of an undisturbed Gulf of Maine ecosystem.

We will be sharing some of the extraordinary pictures Brian made – and the stories that go with them – next week. Stay tuned!
