Jane

The new head of the National Oceanic and Atmospheric Administration is an Oregonian, Jane Lubchenco. Married to fellow OSU marine biologist Bruce Menge, Lubchenco is no stranger to the likes of Jasper, Amelia, Mac, and our beloved Jackie as well as our divers ocean correspondents on this blog. "While traveling around the country developing the Oceans Commission report, Lubchenco said she heard consistently from people that they want clean beaches, healthy and safe seafood, stable fisheries, abundant wildlife and vibrant coastal communities," says the Jeff Barnard's March 19 interview with Lubchenco on Huffington Post. We all say: Go, Jane, Go.

Or Is It Just Hairspray?

"Transport of Asian aerosols across the North Pacific Ocean peaks during the spring season. A mix of aerosols is found in the maritime environment as far west as the North American West Coast, including Asian dust and pollution, local N. American pollution, and new particle formation. Aerosol transport events are arranged in plumes, with pristine maritime conditions prevailing between the plumes," reads the abstract for an article titled Springtime Aerosol Indirect Forcing Across the North Pacific Ocean in Observations and Global Models (click here for more). Are those beautiful ocean clouds off the Oregon coast just evidence of Chinese manufacturers making tacky Christmas ornaments for the jaded American market?

Made it through the tough winter, will be here for summer readers. Thank goodness.

Misty Weather Makes Me All Atwitter


Seabirds love this weather. The backlighting created in these conditions shows up every breathing hole and sandtrail so clearly, as if etched in glass. The buffet is open! Scores of shore birds are scything the air, delighted. When the weather is hot in the Willamette Valley in Oregon, the marine layer moves in, as it has today, creating a lovely world of blue, laying down a magical mist in the lagoon and wreathing Tillamook Head in fog at its base. The lenticular cap, nearly always in place, adds to the mysterious beauty of the day.

Bleary-Eyed but Clear-Headed Mac

Alas, another correspondent has died. Rest in peace, Amelia, we hardly knew you but we miss you still, your beauty and swooping grace. Consequently, our correspondence has been a little like the Macropinna microstoma depicted here, tending to "hang completely still in the water."

Species loss is a little like this: voices silenced, never to be heard from again. How we miss the Salp, for example! This contemplative, perhaps sad, fellow here is our new representative at The Salp, but he's not talking. "Mac," as we shall call this silent fellow, is a good observer, having that transparent forehead, so like a space ship, so we will make comments as if he was as good as talking as he is at looking (but he's not - check out those close-lipped lips).

"The Macropinna microstoma and it has puzzled ichthyologists since it was first described by Chapman in 1939. Macropinna microstoma, also known as the Barreleye fish, has a fluid-filled dome on its head through which the lenses of its barrel shaped eyes can be clearly seen. The fish lives at a depth of 600-800 metres where it spends most of its time hanging almost completely still in the water." From March 4, 2009, blog about fishes. It continues, "it has long been known that the tubular eyes of the Barreleye are good at collecting light; an adaptation to a life deep down in the ocean where light is scarce. The eyes were however presumed to be fixed and the fish was therefore believed to have a very narrow upwards-facing tunnel-vision. Researchers Bruce Robinson and Kim Reisenbichler from the Monterey Bay Aquarium Research Institute (MBARI) has now changed this notion completely by providing evidence suggesting that this fish can rotate its eyes within the transparent dome in order to see both upwards and straight forward. Robinson and Reisenbichler observed that when suitable prey, e.g. a jellyfish, is spotted, the fish will rotate its eyes to face forward as it turns its body from a horizontal to a vertical position to feed." Apparently, when it is alive (!), its eyes are a lovely green in color. Click here if you want to watch Mac on YouTube. He swims very nicely AND YOU CAN SEE HIS BRAIN!!! YUCK?
