Interannual Climate Variability in the West Antarctic Peninsula under Austral Summer Conditions by Eduardo Santamaría-del-Ángel, Mary-Luz Cañon-Páez, Maria-Teresa Sebastiá-Frasquet, Adriana González-Silvera, Angelica-L. Gutierrez, Jesús-A. Aguilar-Maldonado, Jorge López-Calderón, Víctor Camacho-Ibar, Andrés Franco-Herrera, Alejandra Castillo-Ramírez

“…The WAP can be divided into two zones representing two distinct ecoregions: the northern zone (including the Carlini and Gerlache stations) corresponds to the South Shetland Islands ecoregion, and the southern zone (including the Palmer and Rothera stations) corresponds to the Antarctic Peninsula ecoregion. …”

Dark Diazotrophy during the Late Summer in Surface Waters of Chile Bay, West Antarctic Peninsula by María E. Alcamán-Arias, Jerónimo Cifuentes-Anticevic, Wilson Castillo-Inaipil, Laura Farías, Cynthia Sanhueza, Beatriz Fernández-Gómez, Josefa Verdugo, Leslie Abarzua, Christina Ridley, Javier Tamayo-Leiva, Beatriz Díez

“…New measurements of light and dark N₂ fixation rates in parallel with carbon (C) fixation rates, as well as analysis of the genetic marker <i>nif</i>H for diazotrophic organisms, were conducted during the late summer in the coastal waters of Chile Bay, South Shetland Islands, WAP. During six late summers (February 2013 to 2019), Chile Bay was characterized by high NO₃⁻ concentrations (~20 µM) and an NH₄⁺ content that remained stable near 0.5 µM. …”

Biodegradation potential of phenol by pure and defined mixed cold-adapted bacterial consortia from Antarctica by Subramaniam, Kavilasni

“…This thesis reports the isolation of a potential phenol-degrading bacterial strain (AQ5-15) from soil from King George Island, South Shetland Islands, Antarctica. This strain was identified as a member of the genus Arthrobacter based on 16S rRNA gene sequence analysis. …”

Trichocera maculipennis (Diptera)—an invasive species in Maritime Antarctica by Marta Potocka, Ewa Krzemińska

“…Non-native flies of Trichocera maculipennis have been recently observed in the Admiralty Bay area on King George Island, South Shetlands Islands, West Antarctica, 10 years after its first record in Maritime Antarctica (Maxwell Bay, King George Island). …”

Lighten up the dark: metazoan parasites as indicators for the ecology of Antarctic crocodile icefish (Channichthyidae) from the north-west Antarctic Peninsula by Thomas Kuhn, Vera M.A. Zizka, Julian Münster, Regina Klapper, Simonetta Mattiucci, Judith Kochmann, Sven Klimpel

“…In the present study, channichthyid fish (Champsocephalus gunnari: n = 25, Chaenodraco wilsoni: n = 33, Neopagetopsis ionah: n = 3, Pagetopsis macropterus: n = 4, Pseudochaenichthys georgianus: n = 15) were collected off South Shetland Island, Elephant Island, and the tip of the Antarctic Peninsula (CCAML statistical subarea 48.1). …”

High-spatial resolution UAV multispectral data complementing satellite imagery to characterize a chinstrap penguin colony ecosystem on deception island (Antarctica) by Alejandro Román, Gabriel Navarro, Isabel Caballero, Antonio Tovar-Sánchez

“…In this study, the potential of a high-spatial resolution multispectral sensor embedded in a UAV is compared to medium resolution satellite remote sensing (Sentinel-2 and Landsat 8) to monitor the characteristics of the Vapor Col Chinstrap penguin (Pygoscelis antarcticus) colony ecosystem (Deception Island, South Shetlands Islands, Antarctica). Our main objective is to generate precise thematic maps of the typical ecosystem of penguin colonies derived from the supervised analysis of the spectral information obtained with these remote sensors. …”

Exploitation of the SoilPRO® (SP) apparatus to measure soil surface reflectance in the field: Five case studies by Eyal Ben Dor, Amihai Granot, Rony Wallach, Nicolas Francos, Daniela Heller Pearlstein, Bar Efrati, Luboš Borůvka, Asa Gholizadeh, Thomas Schmid

“…The case studies consisted of: (1) generating surface spectral measurements under any atmospheric condition; (2) comparing the performance of the SP to the traditional bare fiber method for vicarious calibration of hyperspectral satellite sensors; (3) assessing water repellency of a soil surface governed by organic matter hydrophobicity; (4) spatial prediction of the rate of water infiltration into the soil profile as governed by the soil surface seal; and (5) using the SP apparatus to measure soil surface reflectance in South Shetland Island, Antartica under severe weather conditions. …”
