Project DescriptionUtilizing commercial cruise ship route, we aim to examine summer biogeochemical cycling and isotopic signatures within the Canadian Arctic Ocean to better understand phytoplankton production as freshwater and terrestrial runoff increases with climate change
Isotope data will also be paired with ship flow-through observations, in which autonomous instruments take continuous measurements of ocean physical and biogeochemical properties via an underway seawater flow-through system. Use of stable isotope tracers for C, N, and H₂O, combined with gross primary production measurements, will create robust insights into freshwater-ocean dynamics, productivity, and supporting evidence into how the CAA is altering global biogeochemical cycles. |
Research Objectives
MS Roald Amundsen Ship Track |
The Ship - MS Roald AmundsenI was invited to join the Norwegian Hutrigruten Vessel - the MS Roald Amundsen - on their Northwest Passage Cruise as a guest scientist. The Amundsen is a science-based cruise aboard a hybrid ship - reducing the ship's fuel consumption and CO2 emissions by 20%!
|
NIVA underway flow-through systemsThe MS Roald Amundsen if outfitted with a flow-through underway system designed by the Norwegian Institute of water Research (NIVA). The underway system allow us to autonomously collect data on water properties (temperature, salinity, oxygen, ect) and chlorophyll a along the entire ship track.

LabSTAF photosynthesis measurements
The Chelsea LabSTAF is a fluorometer designed for measuring phytoplankton productivity using single turnover active fluorescence. The LabSTAF was using during this cruise to measure photosynthetic stress , gross primary production and gross oxygen production of phytoplankton.
