GEOTRACES STATIONS = RED SQUARES

Cruise Overview: [proposal abstract] The Arctic marine system is undergoing rapid change as a result of climate-driven alterations in sea ice cover and surface ocean circulation, which in turn can strongly influence biological productivity, air-sea exchange of climate-active gases (e.g. CO2) and the distribution of contaminants (e.g. mercury, lead). Against this background of climate-driven changes, there will likely be significant expansions of commercial fishing, shipping and exploitation of fossil fuel and mineral resources, particularly in the Canadian Arctic Archipelago (CAA). At present, our ability to fully understand the impacts of these changes and predict their future trajectory is limited by a poor understanding of the interacting chemical, physical and biological processes which shape the functional characteristics and resiliency of Arctic waters. To bridge this critical knowledge gap, we will participate in an international, pan-Arctic field study (Arctic-GEOTRACES) measuring a suite of chemical tracers that provide information on key biological, physical and chemical processes in the Arctic Ocean and CAA. We will map the distribution of these tracers across important hydrographic provinces in the Arctic, following main flow paths of Pacific waters through the CAA to study the biological, physical and chemical transformations which occur as waters move towards the Atlantic Ocean. We will couple our chemical measurements with detailed surveys of water mass structure and circulation, and the results will be incorporated into computer models predicting Arctic Ocean responses to climate change and other human-related disturbances. We will also conduct ship-board manipulation experiments to directly assess the potential influence of ocean acidification (caused by increasing surface ocean CO2 levels) and changes in trace metal concentrations on productivity and species abundances at the base of the Arctic marine food web. Results from our work will provide foundational information critical for sustainable development in the Arctic. Intercalibration activities: Please provide details of how each element was calibrated to meet the requirements of the GEOTRACES programme e.g. use of SaFe standards, collaborative sampling This cruise is part of an intercalibration effort with the GEOVIDE scientists in France. Samples for all key parameters at @ least 3 depths in duplicate at 2 stations will be taken. The samples will be distributed to GEOVIDE scientists for all TEI determinations, in addition to other parameters of interests. The selected deep stations for the intercalibration effort with French GEOVIDE are: Labrador Sea (@ K1, LS2) & Baffin Bay (BB2). The excel sheet with the matching Canada-French scientists is at the end of this document. In addition, see details in the table, where the individual parameters are listed, as well as, in the intercalibration efforts by different groups at the end of these tables.

Other relevant information: The program consists of 2 legs: Leg 2: Leg 3b “Persistent harsh conditions in Hudson Bay, that resulted in the late formation of sea ice, have caused the isolation of some northern communities where fuel and food supplies are getting low. The Amundsen was diverted to help for 12 days during Leg2. However, as of Thursday July 30, the Amundsen is steaming back to the GEOATRACES station which she should reach by Monday. Although much time has been lost, research will continue." Thus, as a result, the cruise planned for Leg 2 will be greatly modified

Intercalibration efforts:

Jay Cullen: routinely reports values for the consensus standards, and participated physically on the 2004 SAFe inter calibration cruise and the Atlantic inter calibration cruise.

Helmuth Thomas: has not participated yet in intercalibration for neither Ba nor Ra. "His" 2007/8 B a data have been measured by Frank Dehairs in Brussels (Belgium), and Frank’s lab might have done. Helmuth did some in-house Ra intercalibration with IAEO standards, but the international in

Helmuth has not participated in i ntercalibration for DIC/TA, however, those data are calibrated against international standards, us ed by all CO2 groups.

Fei Wang: For the Hg/MeHg project

- Cross-over station in Canada Basin: full profile measurements to intercalib with the U.S. Group (Carl Lamborg)

- sample sharing: three samples from different depths in Labrador Sea/Baffin Bay will be sent to the U.S. Group and the German group.

- analyzed a sample from the French cruise GEOVIDE.

Bridget Berquist (Aerosols and Pb & Fe isotope)

I have not participated in any intercalibrations for Pb isotopes yet. I have some samples to do so from Ed Boyle and Kristin Orians, but my student is still coming up to speed and we are developing a new method that I think will work better for us.

As for Fe isotopes and aerosols, they technically do not need to be intercalibrated, but I will with Seth John and Bill Landing respectively. I flew Bill up here to train us and our students in May and I am planning to do my sabattical with Seth in 2016-2017 and will probably run at least 1/2 of the Fe isotope samples in his lab. Plus I am collecting filters and Fe isotope samples to share with both Bill and Seth.

I did send a long 10 extra L bottles to try to grab 2 x 5L samples for the French person doing Fe isotopes, but considering how many TM casts they are doing to meet all the current demands, my guess is that won't happen.
