Abstract: <p>This thesis investigated coloured and fluorescent dissolved organic matter in the Canada Basin, Arctic Ocean from 2007 to 2017. The first interannual time-series of its kind in the Canada Basin incorporated the use of EEM-PARAFAC to validate a seven-component model. Statistical temporal tests revealed (1) an increasing protein-like intensity in the upper polar mixed layer (UPML); (2)… more

Name(s): Creator (cre): Kuhne, Alexandra Margaret, Thesis advisor (ths): Emery, Neil, Degree committee member (dgc): Balch, Gordon, Degree committee member (dgc): Gueguen, Celine, Degree granting institution (dgg): Trent University
Abstract: <p>The rapid expansion of the worldwide population has caused an urgent need for the development of new, more environment-conscious, food sources. In this context, algae, such as Euglena, are of interest thanks to their capacity to naturally produce essential nutrients such as proteins and oils commonly found in animals and plant sources. While these processes are currently being… more

Temporal variation of dissolved organic matter and diffusive gradient in thin films-labile mercury in the Quesnel river, BC, and the Goose Creek tributary of Churchill river, MB

Name(s): Creator (cre): Sarswat, Rishabh, Thesis advisor (ths): Aherne, Julian, Degree committee member (dgc): Gueguen, Celine, Degree committee member (dgc): Sager, Eric, Degree granting institution (dgg): Trent University
Abstract: <p>This study examined dissolved organic matter (DOM) and labile Mercury (from diffusive gradient in thin films (DGT)) in the Quesnel river, British and the Goose creek tributary of the Churchill river, Manitoba. DOM properties were measured with optical measurements of absorption coefficient (a254), spectral slopes (S275-295, SR) and fluorescence indices (HIX, BIX, FI). The DOC proxy… more
