- April 2017 - The Science Magazine published news (follow the link) about the First Release of scientific article ("Greater role for Atlantic inflows on sea-ice loss in the Eurasian Basin of the Arctic Ocean",
DOI: 10.1126/science.aai8204) led by Igor V. Polyakov (IARC, UAF). Among many co-authors from around the world there is also Ilona Goszczko from our lab.

Hard work in progress.
- October 2015 - Ilona Goszczko came back from the next IARC/AARI cruise in the Siberian Arctic - NABOS 2015. The cruise was conducted aboard one of the newest Russian research vessels - RV Akademik Tryoshnikov.
This time, the survey was extended nearly to 180 deg E. Besides physical and chemical oceanography, marine biology was also studied. Moorings deployed during the 2013 cruise were recovered (and re-deployed), six additional moorings were deployed due to co-opperation with AWI, Germany, three ITPs (Ice-Tethered Profilers) and two O-buoys were also launched. Blog from the cruise is avaiable at the project website: NABOS 2015 blog.
- September 2015 - Waldek Walczowski and Agnieszka Promińska took a part in the conference and field workshops under the common title Interdisciplinary Polar Studies in Svalbard (IPSiS) organized in Longyearbyen, Svalbard. Waldek led one of the field workshops while Agnieszka had a talk about the fjords hydrography. More information is avaiable at the meeting website: IPSiS.
- September 2015 - Agnieszka Beszczyńska and Piotr Wieczorek joined the cruise aboard RV Lance to recover and re-deploy moorings located in the Nansen Basin, north of Svalbard. The collected data will provide valuable information about the Atlantic Water inflow to the Arctic Ocean.
- May-August 2015 - Several field campaings were peformed this year: the next summer Arctic experiment AREX 2015 took place aboard RV Oceania. All in all, 213 CTD/LADCP stations were done as well as several towed CTD sections across the West Spitsbergen shelf and slope. Field works in Hornsund provided information about the local processes - glaciers melt and water masses composition. Luckilly, all our people (Agnieszka x 2, Waldek, Piotr, Ilona and Gosia M.) safely came back home.
- January 2015 - During the scientific cruise of the IOPAN research vessel “Oceania” which was conducted in December 2014, starting from the Gdansk Deep, running through the Stolpe Channel and the Bornholm Deep,
ending in the Arkona Basin, a significant increase of the deep water salinity was observed. The salinity increase had been already visible in the western part of the section in September 2014, the survey
in December confirmed previous observations. Higher salinity was noted even in the Stolpe Channel – the single route for the saline inflow to the Gdansk and Gotland deep basins.
The observation of
the great amount of the saline water inflow to the Arkona Basin is proved by oceanographers from the Leibniz-Institut für Ostseeforschung, Warnemünde, Germany. Most likely, we observe the intense
inflow of the saline water from the North Sea, perhaps greater than the previous ones. This is an important message because the last big inflows to the Baltic Sea were noted in 1993 and 2003.
The Baltic Sea’s ecosystem depends on the saline and oxygen-enriched water coming from the North Sea and these inflows have been less frequently observed.
- January 2015 - With the New Year the head of laboratory has changed - until now the position was held by Waldek Walczowski, now Agnieszka Beszczyńska-Möller takes it.
Also the name of the lab has changed - from "Ocean Circulation" to "Observational Oceanography". Other things remain unchanged - we plan new cruises and field works and analyze data from the previous ones ;)
- April 2014 - Waldek Walczowski and Piotr Wieczorek together with colleagues from IGF PAN and Silesia University started this year's field work in Hornsund under the AWAKE-2 Project. More information may be found at the project's website. In May works are continued by Agnieszka Prominska

- February 2014 - Waldek Walczowski, Agnieszka Beszczyńska-Möller and Ilona Goszczko presented their scientific results during the conference "Ocean Sciences Meeting 2014" which took place in Honolulu, Hawaii. The session which was coorganized by Agnieszka applied to the Fram Strait region: "Fram Strait - New insights into physical and biological processes in the Atlantic gateway to the Arctic Ocean and their linkages to climatic changes". Abstracts are available at the meeting's website.
- September 2013 - Agnieszka Beszczyńska-Möller and Piotr Wieczorek participated in the cruise (organized by WHOI and NPI) aboard Norwegian research vessel R/V Lance in the area north of Svalbard.
During the cruise several moorings were recovered and redeployed. Among others there were two IOPAS moorings equipped with the McLane Moored Profilers (MMPs) deployed in summer 2012. One of them was redeployed for the next year.
More infomation is available at the cruise blog: Warming Arcitc - A voyage into a frozen ocean.
- September 2013 - Ilona Goszczko took a part in the NABOS 2013 cruise (organized by IARC, UAF and AARI) aboard Russian research vessel RV Akademik Fedorov
in the Siberian Arctic area. The main field of the research conducted during the cruise was physical and chemical oceanography. To achieve longer time series nine moorings and five ITPs (Ice-Tethered Profilers) were deployed as well.
Moreover, another devices as meteorological buoys SVP-B, O-buoy, glider were also launched. More information is avaiable at the project website: NABOS II website.

- June-July 2013 - The next summer Arctic experiment AREX 2013 took place aboard RV Oceania. All in all 242 CTD stations were done as well as several towed CTD sections across the West Spitsbergen shelf and slope and in the fjords.
Several moorings were also recovered and redeployed. One glider was launched (owned by AWI, Germany). The research was conducted in the frame of two Polish-Norwegian projects: AWAKE II and PAVE and also under Polish research grants: GAME and MIXAR.

- April 2013 - The spring fieldwork under the GAME project already started. Simultaneously reseach was conducted aboard Norwegian vessel RV Helmer Hanssen
(see photos) and in Hornsund fjord, where the Polish Polar Station was the base for the scientists. The fieldwork in Hornsund was guided (until July) by Agnieszka Promińska.

- luty 2013 - R/V "Oceania" wypływa w kolejny, wspólny rejs naszego zespołu i Pracowni Wzajemnego Oddziaływania Morza i Atmosfery w rejonie Bałtyku Południowego. Podczas rejsu wykonane zostaną pomiary holowaną sondą CTD wzdłuż standardowych sekcji, pomiary prądów przy użyciu ADCP oraz badania koncentracji aerozolu morskiego.

- October, 2012 - Joint ART/APECS workshop co-organised by IOPAS (and our laboratory) is placed in Sopot: See Workshop Website
- August, 2012 - The 2012 summer cruise (AREX 2012) to the Nordic Seas finished and R/V Oceania came back to Poland. All in all, we collected 192 vertical CTD/LADCP profiles
in the area north of Norway and west of the Bear Island and Spitsbergen (the most northern station was located at 80°47.71'N). A few moored systems were successfully recovered and redeployed.
More than 300 water samples were collected in order to determinate nutrients content and oxygen isotopes. One ARGO float was launched and it keeps working and sending sets of collected data.
We also continued our research in the west Spitsbergen fjords (Hornsund, Kongsfjord and Isfjord). Field campaign in Hornsund will be continued to early September.

- April-September, 2011 - The second field work in the Hornsund Fjord, Spitsbergen has been done in the frame of the AWAKE Project. Hydrography of the fjord was investigated, especially in the front of the Hans Glacier. Several moored instruments were redeployed in the fjord area in summer. Also meteorological data are continously collected in the Hans Bay,
some glaciological work has been done in cooperation with group from the Silesia University, as well. See Project Website
