The Zooplankton Ecology of Ellis FjordEntry ID: ASAC_379
Abstract: From the abstract of one of the papers:
A study was made of the sub-littoral benthic environment of Ellis Fjord, a 10km-long fjord located near Davis Station, in the Vestfold Hills, Antarctica, over a 15 month period (November 1984 to February 1986). Data were collected by SCUBA diving and underwater photography and were initially analysed by ordination techniques (non-metric multidimensional ... scaling). Ordinations showed substratum type to be the factor most strongly associated with changes in the distribution and abundance of macrobenthic species within the fjord. Other factors shown to be associated with changes in macrobenthic species assemblages were depth, distance from the fjord mouth, bottom slope, shoreline characteristics, current speed, and the presence of low-salinity water at shallow depths during the summer melt. The four major substratum types in Ellis Fjord were sand, rock, Serpula narconensis colonies and Phyllophora antarctica thalli. S. narconensis colonies supported the most species and sand substrata supported the least. P. antarctica is the only macrophyte species which occurred in the fjord. S. narconensis colonies in Ellis Fjord form one of the largest known tubeworm reefs in the world. The assemblages of benthic species in Ellis Fjord were different from those seen at other sub-littoral benthic sites off the Vestfold Hills, and at other Antarctic sites. There was a far greater proportion of filter-feeding species in the fjord than at other sub-littoral benthic sites off the Vestfold Hills. Factors which are thought to have caused these differences are the high level of organic but low level of inorganic input into the benthic system of the fjord, and the absence of anchor ice from the fjord.

Quality The diver made sure not to touch the bottom during the surveys so as not to disturb the assemblages or the sediment (and thus obscure his view).
