Russian-German Cooperation: Laptev Sea System : [2. Workshop Russian-German Cooperation: Laptev Sea System ; St. Petersburg, November 1994]
No full textPREFACE : The Laptev Sea System
The Arctic Ocean, in particular the wide Eurasian shelf seas comprise some of the most sensitive elements of the global environment which are believed to respond at a very early time to Global Change. The renewed interest in the Arctic, the large scale international research efforts devoted to the Arctic, as well as the presently available new technology to carry out research in ice-infested areas, have opened many new avenues to conduct investigations On the variability of the depositional environments of the Eurasian shelf seas. The Laptev Sea is of particular importance in the string of the Eurasian shelf seas because feeding the Transpolar Drift of the Arctic sea-ice Cover it exports relatively the largest amounts of sea ice into the Open Arctic Ocean, because it is farthest away from the influence of the Atlantic and Pacific waters, and because it is under the influence of rapidly changing fresh water fluxes from the Siberian hinterland (Fig. 1, Sea ice drift paths in the Arctic Ocean). The morphology
of the seafloor, the rapidly changing coast lines of the fragil Lena Delta Island frame work as well as the presence of submarine permafrost are examples for the dynamics of the entire Laptev Sea System.

In order to address the natural properties of the Laptev Sea System a joint research project is carried out between a number of Russian and German research institutions under the framework of the "Laptev Sea System Project" (Fig. 2, Research institutions under the framework of the "Laptev Sea System Project"). Every year expeditions are carried out in the area on Russian or German research vessels where multi-disciplinary and binational working groups are addressing some of the identified scientific themes. Results from these joint investigations are then discussed in a series of RussianIGerman workshops which are held alternatively in Russia or Germany.
The second workshop 'Russian-German Cooperation: Laptev Sea System' was held in November 1994 in St. Petersburg in order to assess (1) the state of knowledge of the Laptev Sea and the adjacent continental margin of the deep Arctic, and (2) to develop a research strategy for the marine geosciences in the Laptev Sea and terrestrial werk in East Siberia.
The workshop brought together more than 100 scientists, among them meteorologists, sea ice physicists, oceanographers, biologists, chemists, geologists and geophysicists from various Russian and German research institutions. The main goal of the workshop was to promote and coordinate scientific collaboration among scientists from Russia and Germany. Main emphasis have laid on first scientific results of the expeditions within the scope of the interdisciplinary Russian-German research project 'Laptev Sea System', that is present and past oceanography, ecology, and climatology of the Laptev Sea.
The workshop was organized into serveral sessions which followed various themes of the environment of the Laptev Sea from their present situation to their geological record:
(I) Ciimate and Ice
(11) Modern Environment of the Laptev Sea
(111) Environmental History of the Laptev Sea
(IV) From Siberia to the Arctic Ocean: Land-Sea Connection
(V) Strategy and Plans for Future Work
(VI) Mid-long Term Perspectives
The scientific content of this workshop is documented in this report containing most of the results and discussions. The publication of this volume serves various purposes. It is primarily a forum for scientists working in the Siberian shelf seas, in which the results of many years of research and preliminary shipboard results can be presented. In order to provide all the participants in the workshop with the opportunity for reporting their results, a speedy way of publication was chosen. Thus, each individual author has presented his opinions and views as he or she sees them, reflecting the diversity and complexity of the Laptev Sea system. On the other hand, this volume offers many researchers the possibility of acquainting themselves with methods and results of research into the East Siberian seas as carried out in other parts of the world. Finally, it is hoped that this collection of papers will function as another step toward joint research projects and are base for the expeditions to be carried out in 1995 and the following years. Many of the papers published identify major scientific problems, thus offering new perspectives for future scientific research in polar regions. The nature of the papers, the discussions and the disciplines of the attendees clearly demonstrate that the study of the Laptev Sea System is a multidisciplinary one in an interesting key area involving all branches of the natural sciences, such as ice physics, oceanography, biology and geology, in particular. It thus remains an important example for GLOBAL CHANGE and CLIMATE IMPACT research within international research efforts, e.g. International Arctic Science Committee (IASC), Arctic Ocean Sciences Board (AOSB) or the Nansen Arctic Drilling Programme (NAD).

The editors also made an effort, probably not wholly successful, to edit manuscripts by non-English-speaking authors to make them easier to understand. In this process, we hope we have not changed the meanings of the original papers. Above all we thank Bettina Rohr and Daniel Krüger who kindly assisted in editing the papers. The workshop has been sponsored by the German and Russian Ministries for Research and Technology and the meeting was held from the 21st to the 14th of November in 1994 in the Arctic and Antarctic Research Institute in St. Petersburg. We wish to thank these organizations for their financial and logistic support
Stable dissolved silicon isotopes measured on CTD and underway samples during AMK73 in the Laptev Sea
No full textDissolved stable silicon isotopes were determined in seawater samples collected during the 73rd expedition onboard RV Akademik Mstislav Keldysh (AMK73) in the Laptev Sea in October 2018 under ice free conditions. Seawater samples were filtered inline from Niskin bottles or the ship's underway system, acidified to 0.1% v/v with HCl and kept at 4°C until analysis on land. Samples were measured for δ29Si(OH)4 with reference to international reference material NBS28 on a Nu Plasma II MC-ICP-MS (The University of Edinburgh, School of Geosciences) using the MAGIC co-precipitation method and purified through column chemistry. International standards BigBatch, ALOHA300 and ALOHA1000 were run alongside seawater samples for inter-comparability. Final values were converted to δ30Si(OH)4 using the conversion factor of 1.96 for comparability. Reproducibility is 0.05 and 0.1‰ for δ29Si(OH)4 and δ30Si(OH)4 respectively. This dataset includes salinity, silicic acid concentrations and stable silicon isotope signatures of seawater, which provides useful information on the silicon biogeochemical cycle of the Laptev Sea, as influenced by the Lena river

Ocean Colour Remote Sensing in the Laptev Sea
No full textThe Laptev and Eastern Siberian shelves are the world’s broadest shallow shelf systems. Large Siberian rivers and coastal erosion of up to meters per summer deliver large volumes of terrestrial matter into the Arctic shelf seas. In this chapter we investigate the applicability of Ocean Colour Remote Sensing during the ice-free summer season in the Siberian Laptev Sea region. We show that the early summer river peak discharge may be traced using remote sensing in years characterized by early sea-ice retreat. In the summer time after the peak discharge, the spreading of the main Lena River plume east and north-east of the Lena River Delta into the shelf system becomes hardly traceable using optical remote sensing methods. Measurements of suspended particulate matter (SPM) and coloured dissolved organic matter (cDOM) are of the same magnitude in the coastal waters of Buor Khaya Bay as in the Lena River. Match-up analyses of in situ chlorophyll-a (Chl-a) show that standard Medium Resolution Imaging Spectrometer (MERIS) and Moderate Resolution Imaging Spectroradiometer (MODIS) satellite-derived Chl-a is not a valid remote sensing product for the coastal waters and the inner shelf region of the Laptev Sea. All MERIS and MODIS-derived Chl-a products are overestimated by at least a factor of ten, probably due to absorption by the extraordinarily high amount of non-algal particles and cDOM in these coastal and inner-shelf waters. Instead, Ocean Colour remote sensing provides information on wide-spread resuspension over shallows and lateral advection visible in satellite-derived turbidity. Satellite Sea Surface Temperature (SST) data clearly show hydrodynamics and delineate the outflow of the Lena River for hundreds of kilometres out into the shelf seas
