“The vertical structure of the upper ocean has a big effect on the productivity and distribution of plankton near the surface of the ocean. The vertical structure also affects the concentration of feed, and that affects the behaviour of Bluefin. Vertical structure of the water is controlled by the interaction of heating by the sun, wind-driven mixing, and the density of the water. In offshore areas, or in areas away from river outflows, density is determined mainly by water temperature. The sun warms the surface of the ocean, and the wind blowing over the ocean distributes the heat by mixing the water.
As the sun warms the surface water it becomes less dense and forms a cap sitting on top of the cold deeper water. The temperature changes rapidly at the boundary between the warm less dense surface water and the denser, cooler water below. This boundary is called the thermocline. If you have ever swum in a lake in the summer and found it warm as bathwater in the surface, but freezing cold when you dropped your feet down, you have experienced the effect of a thermocline.
When there is a warm cap on the ocean, the water is said to be stratified (or layered). If the wind has been calm, and the weather sunny, the warm surface layer will be stable, and strongly stratified conditions may develop. In these conditions, Bluefin dive frequently to relatively shallow depths (less than 100 metres). They dive rapidly, feed below the thermocline and return to the surface waters frequently, spending as much as 65% of their time in the upper 10 metres…
Concentrations of feed often occur just below the thermocline. These layers can be seen on an echosounder. Bluefin dive down through the thermocline to feed on these layers. When the water is strongly stratified, the Bluefin dive more frequently to feed. They also dive faster, and stay less time in the deep cold water than they do when the water is well mixed.
Bluefin use this foraging strategy during both day and night. These fish maintain a body temperature warmer than the water, so they remain highly efficient swimmers in cold water..."

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)

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)
