Mineralogical, geochemical, and magnetic signatures of surface sediments from the Canadian Beaufort Shelf and Amundsen Gulf (Canadian Arctic)
Abstract
Mineralogical, geochemical, magnetic, and siliciclastic grain-size signatures of 34 surface sediment samples from the Mackenzie-Beaufort Sea Slope and Amundsen Gulf were studied in order to better constrain the redox status, detrital particle provenance, and sediment dynamics in the western Canadian Arctic. Redox-sensitive elements (Mn, Fe, V, Cr, Zn) indicate that modern sedimentary deposition within the Mackenzie-Beaufort Sea Slope and Amundsen Gulf took place under oxic bottom-water conditions, with more turbulent mixing conditions and thus a well-oxygenated water column prevailing within the Amundsen Gulf. The analytical data obtained, combined with multivariate statistical (notably, principal component and fuzzy c-means clustering analyses) and spatial analyses, allowed the division of the study area into four provinces with distinct sedimentary compositions: (1) the Mackenzie Trough-Canadian Beaufort Shelf with high phyllosilicate-Fe oxide-magnetite and Al-K-Ti-Fe-Cr-V-Zn-P contents; (2) Southwestern Banks Island, characterized by high dolomite-K-feldspar and Ca-Mg-LOI contents; (3) the Central Amundsen Gulf, a transitional zone typified by intermediate phyllosilicate-magnetite-K-feldspar-dolomite and Al-K-Ti-Fe-Mn-VZn- Sr-Ca-Mg-LOI contents; and (4) mud volcanoes on the Canadian Beaufort Shelf distinguished by poorly sorted coarse-silt with high quartz-plagioclase-authigenic carbonate and Si-Zr contents, as well as high magnetic susceptibility. Our results also confirm that the present-day sedimentary dynamics on the Canadian Beaufort Shelf is mainly controlled by sediment supply from the Mackenzie River. Overall, these insights provide a basis for future studies using mineralogical, geochemical, and magnetic signatures of Canadian Arctic sediments in order to reconstruct past variations in sediment inputs and transport pathways related to late Quaternary climate and oceanographic changes.

Hey @geadriana! Thank you for sharing your PhD project with us. Let me share a few tips with you for getting noticed by the #steemstem community. This sounds like an interesting topic. You should write a more elborate post about this, using some sources and explaining what you did and how that works. Try not to just copy and paste your abstract, try to write a "dumbed down" version so you can appeal to a broader audience. Also try to get involved with the steemstem community, read some posts, comment and upvote. Also check out the discord channel if you want. If you have some question or want feedback, feel free to contact me. I am a mentor for #steemstem. Good luck and cheers!
I really appreciate your suggestion I will keep in mind!
Hi, I just followed you :-)
Follow back and we can help each other succeed! @hatu
Hi thanks a lot! I am going to follow you too. See you!
excelente muchos exitos
Muchas gracias espero que la información sea de utilidad. Igual muchos éxitos
Nice work Adriana. I look forward to reading your future posts.
Thanks. I just was sharing my first article, I need start to work in new articles.
Good post. Have an upvote.
I wrote a style guide (link here) for STEM posts that you might find interesting (or not, up to you).
Other than that, your image is obviously yours but in future posts make sure that you properly source your images otherwise the Steemstem curators might down vote you, they are strict (I'm not a curator I just provide some informal Steemtstem mentoring).
On another topic: I live near Toronto and I was thinking of kayaking near Tadoussac, are the whales really plentiful like I here at the mouth of the Saguenay?
Hi, thank you for your comments and suggestions. I really appreciate it, I am learning so, I will try to accept and considerate. about whales I know that it is a good place to see it (Tadoussac) but I am not sure that they more or less abundant that at the mouth of the Saguenay I have never gone.
HI Adriana. This topic makes me wonder what were the ecological changes that underwent along with the geological processes that originated those regions. A former coworker of mine, an enthusiast geologist, taught me that terrestrial ecosystems are driven by the kind of soils available in a given area. Aquatic environments are not so heavily influenced by bottom geology in the whole water column, but it does at the bottom and benthos, as active geochemical processes may govern the water-ground immediate space. Even if it is only sand, granularity can select whose species dwell the benthos and whose don't. I'll check your complete paper. Well done, girl!
Hi. Yes, absolutely everything is connected. In this case we wanted to know about provenance based on geochemical and mineralogical tracer, but there are other work about palynology and bentos. Thank you for checking my paper.
Excelente trabajo, muy interesante, por los resultados obtenidos, además que el esfuerzo realizado, sin igual. Ojala y pudiéramos tener investigaciones similares en zonas venezolanas, pero las limitaciones de toda índole lo impide.
Saludos
