“…On the other hand, the Admiralty Bay is a small area that was intensively sampled during the last 35 years. This could have also accounted for the list of taxa being more comprehensive than elsewhere (see also Siciński et al 2011). In a similar basin (Arthur Harbour, Anvers Island), 69 samples yielded as few as 39 isopod species.…”

“…Isopods are the third most speciose macrofaunal group in the Admiralty Bay, following the Amphipoda (172 species) and Polychaeta (162 species) ). This small (surface area of 120 km 2 ) basin hosts about 23% of all the isopod species described from the Southern Ocean (DeBroyer et al 2011) and about 64% of isopods found off the South Shetland Islands (Castello 2004), although those proportions will certainly change once new species from the deep sea are described ). The high diversity of the Bay's isopods might be associated with a multitude of various microhabitats in the basin (Sicinski et al 2011), and also with the zoogeographic location of the South Shetlands.…”

“…The amount of skeletal fractions increases along the Inlet's axis too (Rudowski and Marsz 1996;Siciński 2004;Campos et al 2013). At the same time, the proportion of sand is higher in the central basin, particularly in the shallower sublittoral (Siciński 2004;Siciński et al 2011).…”

Isopods belong to the most speciose groups of the Antarctic benthic fauna, although the knowledge on their diversity and small-scale distribution patterns is still limited. Here we analyze the diversity of the isopod fauna in the Admiralty Bay, a glacial fjord on the King George Island. The basin is located in the region of the Antarctic Peninsula, the fastest warming area of the Southern Ocean. The study provides important baseline data for future research, particularly with respect to temporal fluctuations in benthic fauna, associated with global changes observed in that part of the world. Forty species of isopods representing 19 families were recorded on the soft bottom of the Admiralty Bay. The analyses were based on 99 quantitative samples collected, within the 20-502-m depth range, with a 0.1 m 2 van Veen grab. The materials for the analyses were obtained in the austral summer seasons of 1984/1985 and 1985/1986. The data revealed a high number of isopod species occurring at a low abundance, the mean abundance amounting to 4.8 ± 8.6 ind./0.1 m 2 . Most of the species occurred at low abundances, 25% of the species being represented by singletons. Caecognathia polaris, the most abundant species, showed the mean abundance of merely 1.2 ± 4.2 ind./0.1 m 2 . Species richness, diversity and abundance of the isopod fauna were much higher in the central basin of the Admiralty Bay than in the Ezcurra Inlet, an area affected by a strong disturbance of glacial origin.

“…Embora sejam conhecidas as dificuldades e limitações dos estudos no ambiente marinho antártico, pode-se dizer que a macrofauna bentônica que habita as águas rasas dessa região é relativamente bem conhecida, principalmente aquela do sistema marinho da Baía do Almirantado, Ilha Rei George (Echeverría & Paiva, 2006;Sicinski, et al, 2011). Esse volume de informações está relacionado ao longo tempo de pesquisas desenvolvidas na região , cujos resultados tem revelado que Polychaeta (Annelida), Mollusca e Crustacea são os grupos mais representativos em diversidade e abundância na macrofauna bentônica (Arnaud, 1974;Knox, 1977;Cantone, 1995;Bromberg et al, 2000).…”

The dataset presented in the paper contains meteorological data from four automatic weather stations (AWS) located in the central and western parts of King George Island (near Arctowski Station and Cape Lions Rump). The dataset includes daily mean, maximum and minimum values of air temperature, relative air humidity, air pressure, wind speed and daily sum of solar radiation. The measurement period ran from 2018.01.01 to 2023.12.31, but it is shorter for two of the stations. Mean values were calculated from measurements taken every 10 min. Direct measurements were used to identify extreme values. The described dataset consists offour files, each for one AWS. It is available in the PANGEA online repository under a non‐restrictive CC BY 4.0 licence for anyone after registration. Despite a strong correlation between the daily mean values of the parameters measured at certain stations, some differences between them were also noticeable. These were due to their location at different altitudes, in a place open to the sea or in a shaded place. Generally, values of wind speed, air humidity, solar radiation and pressure are similar to Arctowski during 2013–2017. The only notable distinction is that the mean annual air temperature and the mean air temperature in the winter months were higher than during 1977–1999 and 2013–2017. The data presented can be used as background for other research projects on King George Island, as well as for analysis of the meteorological conditions themselves. They may also be useful for the evaluation of the management plans of the eight Antarctic Specially Protected Areas or Antarctic Specially Managed Area no. 1 that are located on King George Island.
