As part of NETCARE HQP training, I visited Dr. Maurice Levasseur’s lab at Laval University in Quebec City, from the 4th to the 14th of November, 2014.
The primary goal of my visit to Quebec was to develop on the scientific communication between the modelling and fieldwork communities of the marine DMS research group (i.e. Activity III of NETCARE objectives). This knowledge exchange is crucial, primarily because the quality of modeling work often relies on observational/experimental data collected by fieldwork experts.
In my previous training in ocean modelling, opportunities to work in the field or in a laboratory setting were scarce. Consequently, my knowledge of the methodological aspects of observational and experimental studies were quite limited. During my stay at Laval University, I gained further understanding of DMS(P) measurement techniques (e.g. Gas Chromatography, rate measurements using 35S radiotracers, sampling using Tenax) that are conducted both in the lab and on the CCGS Amundsen, using several types of equipment (see photos below).
I also visited Dr. Michel Gosselin’s lab at the Université du Québec à Rimouski (UQAR), where I was given the occasion to deliver an informal talk on my recent work. This trip was also a great networking opportunity as I was able to meet fellow modellers and observationalists at ISMER-UQAR and the Maurice Lamontagne Institute.
The discussions facilitated the identification of key datasets including particulate and dissolved DMSP concentrations, DMSPd loss rate constant, and DMS yield, all of which can be used to tune our ecosystem-DMS model and further develop model parameterizations.
I’d like to thank the following NETCARE scientists for their support and fruitful discussions during my stay: Maurice, Martine, Margaux, (Laval University) as well as Michel and Marjolaine (UQAR). I’d also like to thank the Takuvik group of Laval University who kindly took me to the Rimouski trip with them.
