“…Brandini & Rebello (1994) reported that the strong turbulence generated by winds resuspended benthic diatoms from the sediment of the inner shallow sections of the Admiralty Bay. In other areas of Antarctic coastal environments, resuspension of sublittoral deposit has been suggested as a primary process for increasing suspended solids (Krebs 1983, Berkman et al 1986, Everitt & Thomas 1986, Dunbar et al 1989, Gilbert 1991, Brandini & Rebello 1994, Klöser et al 1994, Ahn et al 1997. The resuspension of benthic microalgae would significantly affect secondary production and the diversity of nearshore phytoplankton assemblages (Ahn 1996).…”

“…were significantly correlated with SS (Table 2B). The resuspension process would also make benthic diatoms available for benthic suspension feeders (Klöser et al 1994, Ahn et al 1993. Ahn et al (1993) reported that benthic diatoms were abundant in the gut content of suspension-feeding bivalve Laternula elliptica.…”

“…There have been a few studies on microphytobenthic algae, but investigations in the Antarctic and Arctic regions suggest that these microalgae may be important in primary production at certain times of the year (Horner & Schrader 1982, Dayton et al 1986. Suspended benthic diatoms may contribute significantly to total primary production (Picken 1985, Klöser et al 1994, Ahn et al 1997, and benthic diatoms are assumed to be an important food source for benthic animals (Berkman et al 1986, Ligowski 1983. Temporal variations in abundance of benthic diatoms are thus expected to have a significant influence on ecosystems of Antarctic nearshore environments.…”

Microalgal assemblages were measured daily from January to December 1996 at a fixed neritic station in Marian Cove, King George Island, Antarctica. The abundance of microalgae and carbon biomass exhibited clear seasonal variation. Annual mean of total microalgal abundance in surface water was 2.43 × 10 4 cells l -1. Microalgal cell abundance in Marian Cove showed a multimodal distribution of standing crop during the study period. Microalgae started to bloom in October and increased abruptly during November. More than 45% (avg. 3.5 mg m -3 ) of chl a was present in the 2 months November and December, dominated by microplanktonic diatoms (> 20 µm) such as Fragilaria striatula Lyngbye, Licmophora belgicae Peragallo, and Achnanthes groenlandica Grunow. The increase of these diatoms were mainly due to resuspension of benthic microalgae by wind and tidal currents in spring and summer. In contrast, microalgal assemblages in winter were characterized by the dominance of pico-and nanoplanktonic microalgae (< 20 µm) such as Phaeocystis antarctica Karsten, Navicula glaciei Van Heurck, and Navicula perminuta Grunow.

“…data of temperature and salinity in Potter Cove, KGI between September 2007 and December 2008 in 20 m water depth). However, other factors such as increased input of lithogenic particles from underneath melting glaciers and from eroding land surfaces during the austral summer (Ahn et al, 1997;Klöser et al, 1994;Yoo et al, 1999) are bound to primarily affect the sub-littoral limpet fauna in the coastal environment of this volcanic archipelago (Ahn et al, 2002). Plumes of volcanic rock sediments carry high concentrations of heavy metals including Fe, Al, Cu and Zn into the nearshore waters of the South Shetland Archipelago Dick et al, 2007), and similar phenomena are described from areas along the maritime AP (Dierssen et al, 2002).…”

“…While the outer cove is characterized by a depth up to 200 m and mainly rocky hard substrate, the inner cove has a maximal depth of 50 m and is dominated by soft sediments. Further detailed hydrographical and biological features of the cove can be found in Klöser et al (1994), Wiencke et al (1998) and Wölfl et al (2014).…”

Fishing for scavengers: an integrated study to amphipod (Crustacea: Lysianassoidea) diversity of Potter Cove (South Shetland Islands, Antarctica)

Amphipoda from the superfamily Lysianassoidea Dana, 1849 play an important role in Southern Ocean benthic food webs due to their high biomass, abundance and predominantly scavenging mode of feeding. Our knowledge on the lysianassoid fauna, even in well-studied areas of the Western Antarctic Peninsula, is incomplete. Here we report the findings of an integrated study of lysianassoid amphipods of Potter Cove, King George Island/ Isla 25 de Mayo (KGI), combining morphological and molecular species identification (COI barcoding) methods, investigating more than 41,000 specimens from baited traps. For comparison, 2039 specimens from the adjacent Marian Cove were analysed. Ten lysianassoid species were recorded in the deeper outer Potter Cove, whereas the inner cove (<50 m) was dominated by a single species, Cheirimedon femoratus Pfeffer, 1888 (99.44% relative abundance). It is hypothesized that the impoverished lysianassoid fauna inside the meltwater-influenced inner cove represents a 1model for future conditions along the Western Antarctic Peninsula under conditions of increased glacial melting. 2Abyssorchomene charcoti (Chevreux, 1912)
