Multidecadal Warming and Density Loss in the Deep Weddell Sea, Antarctica
15 NOVEMBER 2020 S T R A S S E T A L . 9863 Multidecadal Warming and Density Loss in the Deep Weddell Sea, Antarctica VOLKER H. STRASS,GERD ROHARDT,TORSTEN KANZOW,MARIO HOPPEMA, AND OLAF BOEBEL Alfred-Wegener-Institut Helmholtz-Zentrum fur€ Polar- und Meeresforschung, Bremerhaven, Germany (Manuscript received 16 April 2020, in final form 10 August 2020) ABSTRACT: The World Ocean is estimated to store more than 90% of the excess energy resulting from man-made greenhouse gas–driven radiative forcing as heat. Uncertainties of this estimate are related to undersampling of the subpolar and polar regions and of the depths below 2000 m. Here we present measurements from the Weddell Sea that cover the whole water column down to the sea floor, taken by the same accurate method at locations revisited every few years since 1989. Our results show widespread warming with similar long-term temperature trends below 700-m depth at all sampling sites. The mean heating rate below 2000 m exceeds that of the global ocean by a factor of about 5. Salinity tends to increase—in contrast to other Southern Ocean regions—at most sites and depths below 700 m, but nowhere strongly enough to fully compensate for the warming effect on seawater density, which hence shows a general decrease. In the top 700 m neither temperature nor salinity shows clear trends. A closer look at the vertical distribution of changes along an ap- proximately zonal and a meridional section across the Weddell Gyre reveals that the strongest vertically coherent warming is observed at the flanks of the gyre over the deep continental slopes and at its northern edge where the gyre connects to the Antarctic Circumpolar Current (ACC). -

P oSadaS argentine air Force abstract This paper is a very brief summary of the operations of the argentine air Force (aaF) helicopters in the argentine antarctic. It is a transcription of a Power Point Presentation of the lecture that was given on June 26, 2015 during the X National Helicopter Forum 2015 held at the Institute of aviation in Poland. Keywords : argentine air Force, helicopter operations, antarctic. 1. introDuction The antarctica is a hostile and deserted territory with extremely low temperatures. Winters are long and in summers sometimes the weather conditions do not allow for air operations to last longer than a few hours per day. However,it is possible to operate helicopters safely,following certain guidelines and having the right equipment which is not always very sophisticated. Helicopter operations in the antarctica are very risky and for that reason their preparation has to be very careful in order to make the as safe as possible. It is essential to have fuel, lubricating oils and fluids suitable for low temperatures as well as well-trained people. 2. Brief DescriPtion of the antarctic continent Fig. 1 the antarctic continent,where the South Pole , is located is in the south hemisphere from parallel 60° South. The antarctic Continent has a surface of 14 millions of km 2. during summer the area free of ice is only 280 000 km 2. -

BAS Science Summaries 2018-2019 Antarctic Field Season
BAS Science Summaries 2018-2019 Antarctic field season BAS Science Summaries 2018-2019 Antarctic field season Introduction This booklet contains the project summaries of field, station and ship-based science that the British Antarctic Survey (BAS) is supporting during the forthcoming 2018/19 Antarctic field season. I think it demonstrates once again the breadth and scale of the science that BAS undertakes and supports. For more detailed information about individual projects please contact the Principal Investigators. There is no doubt that 2018/19 is another challenging field season, and it’s one in which the key focus is on the West Antarctic Ice Sheet (WAIS) and how this has changed in the past, and may change in the future. Three projects, all logistically big in their scale, are BEAMISH, Thwaites and WACSWAIN. They will advance our understanding of the fragility and complexity of the WAIS and how the ice sheets are responding to environmental change, and contributing to global sea-level rise. Please note that only the PIs and field personnel have been listed in this document. PIs appear in capitals and in brackets if they are not present on site, and Field Guides are indicated with an asterisk. Non-BAS personnel are shown in blue. A full list of non-BAS personnel and their affiliated organisations is shown in the Appendix. My thanks to the authors for their contributions, to MAGIC for the field sites map, and to Elaine Fitzcharles and Ali Massey for collating all the material together. Thanks also to members of the Communications Team for the editing and production of this handy summary. -
Intercomparison of Ground- and Satellite-Based Total Ozone Data Products at Marambio Base, Antarctic Peninsula Region

This station provides a unique opportunity to study ozone variability near the edge of the southern polar vortex; therefore, many institutions, such as the National Meteorological Service of Argentina, the Finnish Meteorological Institute and the Czech Hydrometeorological Institute, have been carrying out various scientific activities there. The intercomparison was performed using total ozone column data sets retrieved from the ground-based instruments and from Ozone Monitoring Instrument (OMI)—Total Ozone Mapping Spectrometer (TOMS), OMI–Differential Optical Absorption Spectroscopy (DOAS), Global Ozone Monitoring Experiment 2 (GOME2), and Scanning Imaging Absorption Spectrophotometer for Atmospheric Cartography (SCIAMACHY) satellite observations. To assess the quality of the selected data products, comparisons with reference to the Brewer spectrophotometer single observations were made. The performance of the satellite observational techniques was assessed against the solar zenith angle and effective temperature, as well as against the actual shape of the vertical ozone profiles, which represent an important input parameter for the satellite ozone retrievals. -

Accelerated Climate Changes in Weddell Sea Region of Antarctica Detected by Extreme Values Theory

Bucci 31C, 87036 Rende (CS), Italy; [email protected] (V.C.); [email protected] (F.L.); vincenzo.carbone@fis.unical.it (V.C.) 2 National Institute for Astrophysics (INAF), Direzione Scientifica, 00100 Rome (RM), Italy * Correspondence: [email protected] Abstract: On 13 February 2020, The Guardian, followed by many other newspapers and websites, published the news that on 9 February 2020, Antarctic air temperatures rose to about 20.75 ◦C in a base logged at Seymour Island. This value has not yet been validated by the WMO (World Meteorological Organization), but it is not the first time that an extreme temperature was registered in these locations. The recorded temperatures have often been described as “abnormal and anomalous”, according to a statement made by scientists working at the Antarctic bases. Since polar regions have shown the most rapid rates of climate change in recent years, this abnormality is of primary interest in the context of vulnerability of the Antarctic to climate changes. Using data detected at different Antarctic bases, we investigate yearly maxima and minima of recorded temperatures, in order to establish whether they can be considered as usual extreme events or abnormal. We found evidence for disagreement with the extreme values theory, indicating accelerated climate changes in the Antarctic, that is, a local warming rate that is much faster than global averages. -
