  • After five nights in the Taylor Dry Valley it time for the flight back to McMurdo via Marble Point.
    003_DSC00812.jpg
  • The original objectives of the McMurdo LTER were to understand the influence of physical and biological constraints on the structure and function of dry valley ecosystems and to understand the modifying effects of material transport on these ecosystems. Now in the third funding cycle, they are poised to answer more complex questions about biodiversity, the impact of climatic legacies, and ecosystem structure and function.
    001_DSC09404.jpg
  • The LTER project is a study of the aquatic and terrestrial ecosystems in the Dry Valleys region of Antarctica. The Dry Valleys represent a region where life approaches its environmental limits, and unlike most other ecosystems, are dominated by microorganisms, mosses, lichens, and relatively few groups of invertebrates; higher forms of life are virtually non-existent.

  • Lake Bonney and Taylor Glacier. This is the glacier which Scott descended to discover this Dry Valley in 1903, later named Taylor Valley after geologist Griffith Taylor. Rhone Glacier on right.

  • Trekking on Lake Bonney toward the Taylor Glacier. This is the glacier which Scott descended to discover this ice free Dry Valley in 1903.
    011_DSC09522.jpg
  • Polarhaven dive hut and Explorers Cove sea ice, the old ice is in rough condition from years of melt and refreezing, buckling and movement. Dark sand blown from Taylor Dry Valley causes localized melting.
    001_DSC08514.jpg
  • Before going to Antarctica I assumed that the rocks and surface would be monotone and without much variation. Wrongo. Huge variety in the types of rock laying on the ground in the Dry Valleys, many fractured from the extreme temperature variations.

  • Approaching Explorers Cove where Taylor Valley meets McMurdo Sound.
    007_DSC08426.jpg
  • Flight to New Harbor over a windswept McMurdo Sound
    001_DSC08361.jpg
  • Sand blown down Taylor Valley ends up on the sea ice. The snow figures on Mt. Coleman are know locally as "two peeing men". A comforting landmark I can see from Observation Hill 50 miles away at McMurdo Station.

  • Looking east from Lake Fryxell camp toward the Commonwealth Glacier. New Harbor and McMurdo Sound is beyond Coral Ridge in the distance.

    047_DSC09357.jpg
  • I spent three nights at the New Harbor camp, courtesy a generous invite from Sam Bowser, principle investigator of project B-043-M. A description of Sam's project from the NSF website: This project investigates the evolution, genome structure, and associated biomes of foraminiferan protists (forams)... Researchers will dive under the sea ice at Explorers Cove, Cape Bernacchi, and McMurdo Station to collect forams and sediment cores.

  • Back at Lake Hoare, Renee Noffke and Rae Spain firing up Thomas Nylen's 50th birthday cake. Renee was my guide through all my trekking in the Taylor Valley, a huge Thank You to Renee for taking time from her other duties at Lake Hoare to show me around the valley.

  • Unique rock formations are found all over the landscape here, wind shaped ventifacts are everywhere, and these layered sedimentary rocks. Because there is no rain, and few people to interfere, geologic time and action rules the landscape.

  • Lake Bonney, dots are the Polar Haven tents and equipment used by LTER scientists. Below these along the shore you can see the Lake Bonney camp. This was my 3rd day at Lake Bonney when I trekked over the Nussbaum Riegel to Lake Hoare for a three night say.

  • We hiked from Lake Hoare around the terminus of the Canada Glacier to Lake Fryxell to visit the science camp. The camp was unoccupied at the time but soon would be with LTER scientists and researchers. The smaller buildings are individual labs used by researchers. The NSF seems to have gone this way on several of the stations I visited, a modular approach to field camp labs.

  • Split ventifact. Ventifacts are rocks shaped by wind blown sand. Because there is no erosion from rain and little from melting snow, the landscape takes on an unusual appearance we are not used to seeing, something closer to a Mars or Lunar landscape.
