Arctic Ocean: projects/activities

Our objective in present SAON meeting was to know more about SAON activities and plannings to coordinate and promote guidelines criteria for observations in the ARctic Present Spain Research in Arctic is performed mainly for universities and scientific institutions , down the responsability of the Science Department with the support of several national institutions including the Defense Department and Foreign Affairs Institutions are coordinated by the National Polar Committee. The National Scientific Program finance the activities in the polar zones Although our main scientific activities are in Antarctica the activity of Spain in Arctic is rapidly increasing following the fact that Arctic research is a priority task in our Science Program At present we have detected 16 scientific groups working activelly in the differnts fields of Arctic topics (glaciology, meteorology, permafrost, high atmosphere, ecology, physical oceanography, marine geology and biology) These activities are mainly performed in cooperation with Arctic countries Institutions via institutional or researchers contacts About our media to work in Arctic ocean Spain has at present two multiporposes oceanographic research ships In the last years our Ocanographic ship Hesperides has developed two campaigns in The area of Greenland and Svalvars Island in the fields of marine Geology , marine biology and physical oceanography For next summer Hesperides will perform a third oceanographic campaign close to the Atlantic coast of Greenland Other national institutions have been working in marine biology campaigns including fisheries stock evolution Spain has a National Centre of Polar Data were all researchers must enter their raw data gathered in the polar campaigns We considerer , at present , our interest to cooperate inside SAON board, considering that besides other possible cooperation to SAON tasks could be a cooperation with our Polar Data Centre

Monitoring and forecast of the sea and ocean state, support of safety of navigation and marine activities. Main gaps: Additional control is needed for historical data, especially with regard to hydrochemical parameters.

Observe changes in the ecosystem, fluxes of heat, salt, nutrients, CO2, and methane from the seafloor to the atmosphere above, as a function of changing climate in the Pacific Arctic region from the Bering Strait north to the high Arctic. Main gaps: So far unable to go far into the ice for investigation, although the geographical scope of the RUSALCA mission increased in 2009 because of the reduction of sea ice cover. (we were able to reach a northernmost site and to sample as far north as 77°30’N.

The central objectives of the proposed ATMAS project are:  to quantify the photo-chemically triggered NOx and HONO re-emission fluxes from permanently and seasonally snow-covered surfaces in the Arctic near Ny-Ålesund,  to quantify the sources of NO3 in these snow-covered surfaces. In detail, the following scientific objectives of ATMAS can be distinguished: 1. to quantify atmospheric gradient fluxes of HNO3, HONO, particulate nitrogen compounds, and nitrogen in precipitation (snow and rain) above snow surfaces; 2. to quantify the emission of NOx and HONO from the snow pack as atmospheric gradient fluxes 3. to formulate an influx-outflow relationship that can be used in dependence on the snow type for (photo-)chemical atmospheric process models. The results of this research may be expanded to a regional (European) or global scale, to suggest how the NOx and HONO re-emission process and its consequences can be included into regional emission, dispersion and deposition models used in Europe.

The submitted proposal aims to perform the monitoring of the pollen rain in the Greenland atmosphere by distinguishing the local pollen production, relatively low, from pollen grains originating from other Arctic areas. A regular monitoring of the atmospheric pollen content must be performed in order to evaluate the amount emitted and characterise the seasonality of the emission. A comparison with air mass trajectories must allow the modelling of long distance transport

The general objective of this research concerns the quantitative and qualitative study of particulate matter retained in natural (sea-ice and sediment) and artificial (sediment traps) traps in order to determine the main origin (autochtonous and allochtonous) and the relative importance of different fractions of particulate matter and to follow their fate in the environment. To quantify the autochtonous origin of particulate matter, primary production, nutrient uptake, biomass distribution, phytoplankton community structure and fluxes in the first levels of the trophic chain will be investigated. Studies will be conducted in the sea-ice environment and in the water column and compared to the particle fluxes measured both in the water, using sediment traps and in the sediment, by radiometric chronology, in order to estimate the different contribution of these habitats to carbon export to the bottom. The zooplankton will be identified and counted and primary production, nutrient uptake and phytoplankton dynamics will be related to hydrological structure and nutrient availability in the environment. The Kongsfjord results particularly suitable for the main objective of this research as it is influenced by important inputs of both atmospheric (eolic and meteroric) and glacial origin and is characterised by a complex hydrological situation which may promote autochtonous productive processes, thus determining important particulate fluxes.

Our broad area of enquiry is the role of polar regions in the global energy and water cycles, and the atmospheric, oceanic and sea ice processes that determine that role. The primary importance of our investigation is to show how these polar processes relate to global climate.

Our central geophysical objective is to determine how sea ice and the polar oceans respond to and influence the large-scale circulation of the atmosphere. Our primary technical objective is to determine how best to incorporate satellite measurements in an ice/ocean model.

To understand and model the processes by which Arctic deep water is formed on continental shelves by the modification of inflowing Atlantic and Pacific waters.

To develop the next-generation Navy operational ice thickness and movement model.
