Webb16 maj 2024 · An oxygen minimum zone in the ocean is often called a “dead zone” because the dissolved oxygen levels are so low that most sea creatures can’t survive. There has been an increase in the number of low-oxygen zones, which poses big threats to oceans. This is urgent, since — just like humans on land — marine animals need oxygen to survive.

WebbThe oxygen minimum layer (oxygen 180 mol/kg) in the AZ is nearly coincident with the temperature maximum. The oxygen minimum is a very large-scale feature that comes from the deep waters north of the ACC, whereas the temperature maximum is found only south of the PF where the sea surface is near the freezing point. WebbThe thermocline depth appeared to have the greatest influence of all the physical factors on the vertical distribution of the copepod species. The vertical distribution of many species was truncated in the region of the oxygen minimum layer with very few species found below this layer.

Webb20 juni 2024 · The measured DO was higher at the surface and lower at depths, with a distinct oxygen minimum layer between 600 and 900 m (Figure 3a ). High DO was present between 60 and 80 m during summer when vertical stratification was strong. Along the BGC-Argo track, there was strong mesoscale variability in the DO distribution.

An oxygen minimum zone (OMZ) is characterized as an oxygen-deficient layer in the world oceans. Typically found between 200m to 1500m deep below regions of high productivity, such as the western coasts of continents. OMZs can be seasonal following the spring-summer upwelling season. Upwelling of nutrient-rich water leads to high productivity and labile organic matter, that is respired by heterotrophs as it sinks down the water column. High respiration rates deplete the ox…
