How cool are these pancakes?! Of all the ocean art out there, and ocean-related food, these are among our faves – marine invertebrate pancakes, straight from Saipancakes. Their talented creator, math-teacher-turned-Saipan-Dad Nathan Shields, needs to package these – they’re waaayyyy better than Eggos.
It looks like a molar tooth drenched in gold, or maybe a metallic mylar birthday balloon. But this is a bathypelagic ctenophore, photographed near the Mid-Atlantic Ridge of the Atlantic Ocean. The ‘bathypelagic zone’ is the layer of the ocean about 3,000 – 13,000 feet deep, sometimes called “The Midnight Zone”, because there is no light at these depths.
Ctenophores are known to many as comb jellyfish – they have eight rows of cilia that look like combs, which they use to move through the sea. Researchers say this one anchors to the seafloor with its tentacles.
Researchers collaborating on the Census of Marine Life returned from an expedition to the Mid-Atlantic Ridge, brimming with findings of new creatures, reporting on unexpected abundance of some already-known creatures, and sharing stunning photos (like this one) with the world.
“This expedition has revolutionised our thinking about deep-sea life in the Atlantic Ocean. It shows that we cannot just study what lives around the edges of the ocean and ignore the vast array of animals living on the slopes and valleys in the middle of the Ocean,” said Professor Monty Priede, Director of the University of Aberdeen’s Oceanlab.
Video released by the Deepwater Horizon Response team from the oil leak site shows the sheer volume of crude spraying into the deep sea 24/7 (visible especially starting at 1:58)
And we got word from the EPA yesterday that it has approved further use of chemical dispersants, both on the surface and underwater, even though EPA notes
“The effects of underwater dispersant use on the environment are still widely unknown, which is why we are testing to determine its effectiveness first and foremost. If it is determined that the use of this dispersant underwater is effective and that BP may continue its use, the Federal government will require regular analysis of its impact on the environment, water and air quality, and human health. We reserve the right to discontinue the use of this dispersant method if any negative impacts on the environment outweigh the benefits.”
Testing on a grand scale and then deciding over time if the negative impacts might outweigh the benefits? Of course, the relatively slow pace of scientific research means the determination of negative impacts will lag far behind any immediate ‘benefits’ of the chemicals breaking up oil slicks.
Countless known and little-known sea creatures in the waters of the Mississippi Canyon and beyond are being inundated with the gushing oil. Adding a brew of mystery chemicals to the mix is irresponsible at best – our government can do much better by us and by our environment than sanction wild and desperate use of untested chemicals.
Among the many creatures in the Gulf’s deep waters? Bioluminescent sea creatures like jellyfish – scientists have been working for years to unlock the secrets of this phenomenon.
Our ocean pic of the week — a planktonic jellyfish with bright green fluorescent tentacles. The red fluorescence in the middle of the jellyfish is from chlorophyll in a recent meal of algae.
This pic is from NOAA’s Operation Deep Scope 2005 Expedition – a research cruise in the Gulf of Mexico’s deep waters off Florida.
Some scientists on the expedition set out to study light in the ocean – color, fluorescence, polarization, vision and bioluminescence.
Dr. Edith Widder, a senior scientist on the trip, said her first sight of luminescence in the ocean’s depths changed her life:
“Seeing lights in the ocean – the living lights of bioluminescence observed from a submersible – is the event that set me on my uncommon career path … I was also convinced that bioluminescence had to be one of the most beautiful and important phenomena in the ocean. It seemed like it was everywhere and there was so much of it.”
