Nutrient matters in saline lakes of McMurdo Oasis in the 1976-77 summer season
In the 1976-77 austral summer, the distribution of nutrient matters was studied for the waters of Home Lake at Cape Royds of Ross Island, Lake Vanda in the Wright Valley, Lake Bonney in the Taylor Valley and Lake Joyce in the Pearse Valley in the dry valleys of Victoria Land in the Antarctic.
