Hawaiian Green Turtle

The weather was so nice out on Midway... very different than in November. Warm summer days with a night light breeze, just enough to take the edge off without keeping you out of the water... unless you are an endangered Hawaiian Green Turtle. I had a good feeling when we found three turtles hauled out on a beach in Kona. The beach was pretty busy but there were signs asking people not to harass the turtles as they were "resting". Most people obeyed much to my delight.

Once we got to Sand Island on Midway Atoll (the only island of the three that is populated by humans) I checked out Turtle Beach. On one day I counted 15 turtles hauled out and saw several more cruising the shallow waters near the beach. The turtles are not actively nesting on Sand Island so he popular theory is that they are hauling out because of the high predator load in the waters surrounding the Atoll. Tiger sharks and Reef sharks are found in the waters in great abundance. In the late summer they feed on the unfortunate albatross chicks that don't learn to fly quickly enough. We spotted four different Reef sharks by the pier on a day we were returning from a snorkel trip. The good thing about the shallow water is that dark shapes like turtles, sharks and seals stand out from a great distance. It would be very difficult for one of these critters to sneak up on you if you were in the water.

There are other hazards out there for the turtles, man-made hazards.

Plastic bags floating in the ocean look a lot like jelly fish, a turtles favorite food. Once the bag is ingested it blocks the turtles stomach opening so it can't take in any real food. The turtle then starves to death. What you can do to help: Use a cloth bag for your groceries and keep using it. If you forget to bring your bag to the store, ask for paper which can then be recycled. Participate in a Beach Clean up day. Pick up any errant plastic bags you see in the street and place them in a proper waste receptacle.

Ghost nets: Turtles don't have very good eyesight. They can easily become entangled in netting that is adrift in the ocean and will drown. They don't have gills, they need to surface to breath! In 2003, NOAA and the Coast Guard removed 100,000 kilograms of derelict netting from the reefs in the Northwest Hawaiian Islands... in 2004 there was another 100,000 kilograms to be removed. The collected debris is transported to Honolulu where it is cut into managable pieces and then incinerated to create electrical energy which is then used by the residents of Oahu. In 2003 that was 111 metric tons which was enough to power 42 homes for a full year, the equivalent of 120 barrels of oil. This debris is worth far more out of the ocean!

TURTLE!

I managed to make it back out to the Farallon Islands. More importantly, I managed to do it without getting sick. Out of 20 people on the boat, 7 people were down for the count due to sea sickness.

I headed out because I had heard there had been Blue Whale spotted. Unfortunately there was a storm at sea that stired up the currents - the whales had not yet returned to their feeding cycle. We did spot the Blue but at the end of the day and from afar.

The absolute highlight of the trip for me was an encounter with a Leatherback Turtle. If you know me, you know I ADORE turtles... if you don't know me... I ADORE turtles. When I first moved to San Francisco I took a tour to the Farallons and found a Leatherback - we got some photos which I am sure were nothing short of amazing... and the print lab lost the film.

It's pretty rare in life that you get a second chance. Even more rare to have a second chance with an endangered species. So I am counting my blessings on this encounter. The Turtle was so nice and mellow and didn't even care that we drifted along side of him for a time.

The Mola Mola (Ocean Sunfish) was the icing on the cake for the day!
