“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..."

With the #OpenStreetMap website’s new #VectorTiles, it’s nice to see that we can zoom in to level 23! Unfortunately, if the vector coordinates are not stored with OSM’s 7 decimal places for higher-zoom tiles, then what’s the point of all that zoom? 👀

Is anyone aware of interactive webmaps which integrate sound based on geographic position? e.g. play birds chirping if map shows forest.
I think there is great potential to transport additional information or even feelings with soundscapes in maps, yet I have barely seen it.
