Ephemeral wetlands in the Antarctic dry valleys alternate as sites of in situ net primary production when inundated and sources of organic matter for eolian export when desiccated. Evidence of this switch was obtained from observations made in two field seasons (2001 and 2003), coincidentally separated by a season of exceptionally high water yield from nearby glaciers (2002). In 2001, organic matter on soil surfaces adjacent to several ponds in Taylor Valley often exceeded 500 g C/m2. One pond… CONTINUE READING
