Sara Darychuk

Heyo! I'm Cameron, a prospective grad student with 5+ years of field experience in avian & ungulate ecology,tracking tech & envi ed. I'm looking for leads on MSc/PhD ops to study spacial/pop/behavioral ecology & conbio. Please RT or send tips on the grad search process. Thanks!

I will forever be passionate about supporting #WomenInSTEM 🔬⛰️🌱Today I am grateful for my fellow female scientists and for my dear friend @chesnokova_anya, an incredible researcher and one of my most influential mentors 💪 #WomeninScienceDay

The poster is available from: …21fallmeeting-agu.ipostersessions.com/Default.aspx?s…

Anyone interested in seeing some SAR estimates of snowmelt check out my #AGU21 poster this afternoon! I will be available on chat from 1200- 1400 and on video from 1500 - 1600 PST❄️❄️❄️

@mouthofmorrison @SistersofSAR As for coherence and look angle, I will have more information soon! We are currently working on a manuscript that explores these variables in the Lajoie Basin, British Columbia 😊

@SistersofSAR Awesome. Love learning about this stuff. Some questions for @darychuk: - Why does low backscatter values correlate to snowpack saturation? - Is correlation peculiar to C-band? - Does look angle affect the properties of the backscatter? - Do timeseries have to be coherent?

1/4⭐️#SAR_STAR Friday! Today we feature @darychuk from Mission, British Columbia 🇨🇦. She has a BSc in #EnvironmentalScience, and is in the third year of her #PhD at 🇨🇦 @UNBC. Her research focuses on the use of #SAR for studying ❄️ snowpack 🌨️ dynamics! #WomeninScience

@mouthofmorrison @SistersofSAR We have not yet experimented with other SAR bands, but I would expect the relation to be more difficult to detect with wavelengths than can not penetrate the snowpack as deeply.

@mouthofmorrison @SistersofSAR Hence, in theory, the lowest backscatter signal should then correspond to your 'wettest' or most saturated snow pack. There was a great paper on this by Carlo Marin that was published in the Cryosphere in 2020!

@mouthofmorrison @SistersofSAR Thanks for the questions @mouthofmorrison! To try and put it simply, C-band SAR signals can easily pass through dry snow; however, they are interrupted by liquid water in the snowpack (lowering backscatter values).

@SistersofSAR @UNBC And thanks to @JosephShea for being not only a great supervisor but a great photographer as well!

Was snowmelt a contributor to streamflows during the #bcstorm floods? Survey says

A quick look at this morning RCM radar image (30m pixel resolution) over the Sumas Prairie near Abbotsford. Zoom-in of the affected agricultural land in the region, seen as black in the images. #BCFlood #CdnAg

Fraser River flooding, from space. Amazing movement of topsoil into the sea. Stay safe, all. @NASA

High resolution satellite imagery of Vancouver, BC today! The Fraser River is normally pretty turbid, but that's a lot of sediment being deposited into the Strait of Georgia today. #yvr #bcstorm #bcfloods

Highway 1 in #Abbotsford shut down due to rising flood waters

Mind blown.🤯There is a thing called 'whale carbon'. It's the amount of carbon stored in whale bodies, including "deadfalls" sunken on the sea floor. And if we restored global whale populations to pre-whaling levels, they'd sequester 1.7 billion tons of carbon/year. #bluecarbon

Our eyes have been on the dismantling of women’s rights in Afghanistan but in the US men have decided Texan women don’t have rights over their own bodies. Abortion bans threaten women’s right to health, life & bodily integrity.

listen, a tree told me this was fine so i don’t need your judgment
