In Deep Lakes, Mixing is Disappearing

With a depth of nearly 600 meters, Crater Lake in Oregon is the deepest lake in the United States. It’s known for its brilliant blue hue and startling clarity. But, like other deep lakes, Crater Lake is changing as temperatures warm. It’s edging ever closer to a day where its deep, cold waters no longer mix.

Although the details of mixing vary from lake to lake, older records show that most deep lakes would overturn and fully mix on a frequency that ranged from twice a year to every seven years. This overturning happens when winds push frigid, near-frozen water. As that water approaches the shoreline, it gets forced downward, where the pressure at depth makes the cold water denser still, causing it to sink beneath the warmer water layer near the lake bottom. That kicks off larger-scale mixing that redistributes oxygen, nutrients, and toxins in the lake.

When this regular mixing stops, the entire ecosystem gets affected. Over time, oxygen gets depleted in deeper in the lake, leaving a dead zone unable to support fish and other aquatic life. Meanwhile, longer and warmer growing seasons favor phytoplankton and algae that cloud the waters and disrupt a lake’s unique ecology.

For a much more detailed look at deep lake mixing and the changes we’re seeing, check out this article over at Quanta Magazine. It’s a longer read but well worth your time. (Image credit: N. Perez Aguilar; see also: Quanta Magazine)

"KEY POINTS:
• Groundwater inflow enhances winter lake ice thickness by stabilizing the water column and reducing vertical mixing
• Ice responses to groundwater are strongest in coastal zones due to higher flux and shallow bathymetry
• Including groundwater in coupled models improves understanding of ice formation and winter lake processes…”

Blooming in Blue

Summers in the Barents Sea — a shallow region off the northern coasts of Norway and Russia — trigger phytoplankton blooms like the one in this satellite image. The blue shade of the bloom suggests the work of coccolithophores, a type of plankton armored in white calcium carbonate. This type of plankton thrives in the warm, stratified waters of the late summer. Earlier in the year, the water tends to be nutrient-rich and well-mixed, conditions which favor diatom plankton species instead. Their blooms appear greener in satellite images. (Image credit: W.

« Stratification theories suggest that social background and cumulative advantage dominate cognitive ability as determinants of high occupational success. This leads us to hypothesize that among the relatively successful, average ability is concave in income and prestige. »

Yes, not hard at all, MAIS les graines ne germeront que si elles ont été "stratifiées" par une exposition au froid en hiver ou dans un réfrigérateur. Ce site est l'un des nombreux avec des détails pour vous aider.

Stratification is required for many seeds to germinate better. Instead of putting seeds in a wet paper towel in the fridge, I put the seeds into some half composted tree leaves outdoor while it rains in winter. A major disadvantage is that some birds will scratch around and eat the seeds. But that's ok. I don't need a 100% success rate.

Stratification and its hormonal biochemistry is being studied in recent years. Here is a paper.

@dale Amazing. Thank you for going slowly enough to notice it, & for sharing, & via the frame of your own art!

A refreshingly self-referential take on #StreetArt ~ I wonder what an #artist like #Magritte or #Duchamp would think..

Given the current state of #class #stratification I sense they may have approved of this playfully-pointed piece.

⚡ Using my first post to announce that I am delighted to have joined the fantastic team of Prof. Anette Fasang at her chair of #microsociology back @HumboldtUniBerlin as a Research and Teaching Fellow. I'm really looking forward to reintegrating into the lively #Berlin research community after a wonderful Postdoc at the Department of #Sociology @UniOxford.

I will be working on topics around #familydynamics, #wealth, #lifecourse, #stratification, #gender, #socialdemography etc.

Why do so many couples look alike? It is tempting to immediately interpret this pattern of assortative mating as resulting from preferences. This paper gives a very complete review of alternative explanations. #science #biology #matechoice #homogamy #convergence #stratification
