    Guest Post by Willis EschenbachI’ve spent a good chunk of my life around, on, and under the ocean. I worked seasonally for many years as a commercial fisherman off of the western coast of the US. I’ve frozen off my begonias setting nets in driving sleet up in the Bering Sea. I’m also a blue-water sailor with a Pacific crossing under my belt, and a surfer, and both a sport and a commercial diver.Plus I’m eternally curious, so I have read about and studied the ocean all my life.Based on both my experience and my knowledge, I have written...

  • Destruction of Giant Algae Doughnut Threatens Lake Michigan (Quagga mussels eating phytoplankton)

    An invasive species of mussel called quagga has recently begun eating its way through the phytoplankton population of Lake Michigan, which could have dire effects on the lake's ecosystem, scientists now warn. A giant ring of phytoplankton (microscopic plants such as algae) was discovered in Lake Michigan in 1998 by Michigan Technological Universitybiologist W. Charles Kerfoot and his research team. The "phytoplankton doughnut" is formed when winter storms kick up nutrient-rich sediment along the southeastern shore of the lake. The disturbed sediments begin circulating in a slow-moving circle with the lake's currents, which provides a massive supply of food for...

    Watts Up With That ^ | July 30, 2010 | Anthony Watts
    Now its a Phytoplanktonic panic Posted on July 30, 2010 by Anthony Watts Borrowing a phrase from NSIDCs Dr. Mark Serreze, Phytoplankton are now apparently in a Death Spiral. See Death spiral of the oceans and the original press release about an article in Nature from a PhD candidate at Dalhousie University, which started all this. Im a bit skeptical of the method which they describe in the PR here: A simple tool known as a Secchi disk as been used by scientists since 1899 to determine the transparency of the worlds oceans. The Secchi disk is a round disk,...

    Atmospheric scientists have reported a new and potentially important mechanism by which chemical emissions from ocean phytoplankton may influence the formation of clouds that reflect sunlight away from our planet. This intimate connection between life and the environment of Earth could have profound implications for the future of our planet's global ecosystem. Discovery of the new link between clouds and the biosphere grew out of efforts to explain increased cloud cover observed over an area of the Southern Ocean where a large bloom of phytoplankton was occurring. Based on satellite data, the researchers hypothesized that airborne particles produced by oxidation...
  • Satellite observes agricultural runoff causing algal blooms

    Direct Link Discovered Between Agricultural Runoff And Algal Blooms In SeaScientists have found the first direct evidence linking large-scale coastal farming to massive blooms of marine algae that are potentially harmful to ocean life and fisheries. Researchers from Stanford University's School of Earth Sciences made the discovery by analyzing satellite images of Mexico's Sea of Cortez, also known as the Gulf of California - a narrow, 700-mile-long stretch of the Pacific Ocean that separates the Mexican mainland from the Baja California Peninsula. Immortalized in the 1941 book Sea of Cortez, by writer John Steinbeck and marine biologist Edward Ricketts, the...

    A combined oceanographic and geologic image today. Click the image below to see the larger image, which is only 515 MB. I was struck both by the phenomenon caught by the satellite and also the amazing colors of the Namibian landscape. See the link at the bottom for another Namibian feature of note, which is north of the area seen in this image.

    Breakaway Bergs Disrupt Arctic Ecosystem WASHINGTON, DC, May 9, 2002 (ENS) - Another large iceberg has newly calved from the Ross Ice Shelf, the National Ice Center has confirmed. Iceberg C-18 is the latest in a series of bergs to break away from the warming Antarctic ice mass. National Ice Center analyst Judy Shaffier spotted the new iceberg Sunday while performing a weekly satellite image analysis of the Ross Sea using an image from the Defense Meteorological Satellite Program. The Ross Ice Shelf is a large sheet of glacial ice and snow extending from the Antarctic mainland into the...
