Marine Monday: Olive Sea Snake
When you think of ocean animals, snakes are not usually the first thing to come to mind, but they live as comfortably underwater as they do on the ground. Today’s Marine Monday features one of these swimming snakes, the olive sea snake.
Olive sea snakes live in corals in the waters above Australia. Divers should be cautious around these olive-brown snakes, as they will swim right up to anything that catches their curiosity, and they will bite if they feel threatened. An olive sea snake bite is venomous and can be fatal.
But don't worry, beachgoers have little to fear from this snake. Olive sea snakes live and hunt within their own small territories in coral reefs and rarely enter open water.
One cool thing about olive sea snakes is that they have a nine-month gestation period and give birth to live young, just like us! But their babies come in litters of five and are the size of a human finger, plus they grow up to be venomous sea snakes, so the similarities end there.

Exploring Uncharted Territory off Oregon's Coast
This is part of a series of posts about our Pacific Hotspots expedition. Today's highlights: On their final day in Oregon, the crew ventures into uncharted territory and finds a variety of corals and fish.
Oregon Leg, Day 5
Friday was our last day aboard the R/V Miss Linda and it could not have been a better day for working on the ocean. We left the Charleston Marina at 7 AM bound for the nearshore reef south of Cape Arago and west of Seven Devils State Park.
As we were working in and out of Charleston today, we invited guests to join our expedition including Dr. Craig Young, the director of the University of Oregon’s Oregon Institute of Marine Biology and Dr. Jan Hodder from the Oregon Institute of Marine Biology.
The University of Oregon has been operating marine studies in the Charleston area since 1924 with year-round research programs beginning in 1966. Dr. Young and his graduate students have made hundreds of deep dives in submersibles and sailed on oceanographic ships in the Atlantic, Pacific and Indian Oceans. Yet surprisingly, nobody has ever been to the areas we went Friday with a Remotely Operated Vehicle (ROV) and underwater camera.
Exploring Oregon's Rocky Reefs
This is part of a series of posts about our Pacific Hotspots expedition. Today's highlights: rockfish, basket stars and hydroids.
Oregon Leg, Day 1
Last night our six Oceana crew slept aboard the R/V Miss Linda, tied to the dock at the Charleston Marina. The captain and his two crew members arrived at dawn, started up the engines and walked our tired souls through an important safety briefing. The Miss Linda is a 76-foot research charter vessel that formerly worked these Pacific Ocean waters as a commercial fishing boat. The captain is experienced, confident and will certainly lead us safely through our five-day expedition.
Our objective today was to get situated working aboard the Miss Linda with our Remotely Operated Vehicle (ROV) while exploring a large area of rocky reef just south of Cape Arago. Over the next four days we will use the ROV to capture high definition video footage of some of the most remote and rugged areas off the southern Oregon coast.
By our third dive this afternoon, five miles offshore and over 150 feet down, the Miss Linda crew and Oceana crew were in sync. With each drop of the ROV we saw schools of rockfish hovering over a rich tapestry of seafloor life.
Studies Begin to Reveal Effects of Gulf Oil Spill
A week from today marks the one year anniversary of the BP oil spill, and the effects of the spill on the gulf’s ecosystems and wildlife are beginning to come into view, though the full effects won’t be understood for years.
This week the New York Times published an overview of the latest findings. The good news is that although miles of marsh are still oiled and tar balls continue to wash up on beaches, the Gulf of Mexico can thank its oil-eating bacteria for digesting some of the crude oil and the methane gas.
Not all the news is so good, however. Here are some of the latest findings about Gulf wildlife:
Oceana Proposes a Canary Islands MPA
Last week, in a culmination of several years of work, our European colleagues presented a proposal to protect 15% of the marine area around Spain’s Canary Islands. If the proposal is accepted, it would multiply the current protected area by 100.
Here’s the back story: In 2009 the Oceana Ranger, our research catamaran, sailed to the Canaries, which are off the coast of Morocco. Over the course of two months, the crew documented the seamounts and seabeds of the archipelago, and found a dozen species never before seen in the area, and filmed many rare species, including three-foot-tall glass sponges, Venus fly-trap anemones and lollipop sponges. (For more on the Canaries see this piece from our magazine last winter.)
The protected area would harbor many other threatened species in the area, such as sea turtles, deep-sea sharks, seahorses, the giant grouper, blue and right whales and the white gorgonian.
Photos from the Alabama Alps
Yesterday you heard about the Latitude’s foray into the Alabama Alps. Today, photos!
Here are some of the cool creatures our deep-sea ROV captured on camera. Which one's your favorite?
Special thanks to Nautica, whose support made our use of the deep sea ROV possible!
Good News from the Alabama Alps
Today’s expedition update, which comes to you from scientist-in-charge Dr. Michael Hirshfield, contains some good news about the Alabama Alps:
Sunday, September 12
After making several transects of the Alabama Alps today and comparing Oceana’s observations with those from previous scientific investigations, we believe to have a fairly good snapshot of the area.
Based on what we saw from the ROV footage and CTD scans, there are no obvious signs that this area was harmed by the recent Deepwater Horizon oil spill. Here’s Oceana conducting a CTD scan:

Fact of the Day: Christmas Tree Worm
The subject of today’s FOTD is the Christmas tree worm, or spirobranchus giganteus for those of you who prefer the scientific name.
Christmas tree worms are embedded in the surface of corals by the calcareous, shell-like tubes in which they live. They have two beautiful, feathery spirals (which look like little Christmas trees) that extend into the water column and are used for filter-feeding and breathing. At the slightest disturbance, the Christmas tree worm retracts into its tube in the coral for safety.
My favorite thing about these worms is their variety of vibrant colors and patterns- check it out!
See you tomorrow for another random FOTD! And if you’re like me and you just can’t wait for more, go to Oceana.org/Explore.
Spill May Be Headed for Florida Keys
It’s hard to believe it has been almost a month since the Deepwater Horizon exploded and sank, and yet this weekend was the first sign of any kind of progress to contain the disaster bleeding into the Gulf.
Using a mile-long “insertion tube” to siphon the oil to a tanker ship, BP captured some of the oil gushing from the Gulf of Mexico seabed -- though the company still hasn't made any progress toward actually stopping the flow.
Scientists from NOAA are worried that the still-gushing oil spill will enter the powerful Loop Current, if it hasn’t already, which would take it through the biodiverse barrier reef that makes up the Florida Keys and up the East Coast.
Oil Leak Threatens Great Barrier Reef
This weekend, a Chinese coal tanker ran aground on one of our planet’s most diverse and delicate ecosystems: Australia’s Great Barrier Reef.
The tanker, badly damaged and in danger of breaking apart, has already spilled 2 metric tons of heavy oil into the shoals off Queensland's coast in the Great Barrier Reef Marine Park. In 2007, the same shipping company, COSCO, was linked to the major spill in the San Francisco Bay.
This is Australia’s third recent major disaster, following the massive oil spill off Queensland and the Timor Sea oil platform blowout. Oil is extremely toxic to marine life and the damage to habitat can persist for years, even decades after a spill.
In the wake of the Obama administration’s recent decision to open up a huge swath of U.S. waters to offshore drilling, this should serve as a warning against adding more oil to our oceans.
