Wind driven is driven by the wind stresses at the surface of the ocean. If you could magically turn off all the winds, then perhaps not at that instant, but over some days or weeks, all the wind driven currents in the oceans would cease. Now, the thing to remember about both of ...
However, during a globally warmer period 3 million years ago, warm waters in the eastern tropical Pacific supported higher productivity than in the recent past. We reconstructed the surface temperature and productivity from four sites in the eastern Pacific over the last 3 million years to assess ...
In tropical regions, the importance of the ASV is less prominent and displays a variance of the same order of magnitude compared to the annual cycle, or the El Niño/Southern Oscillation in the Pacific Ocean8. The trade winds are generally steadier than mid-latitude flows but still exhibit ...
A strong negative relationship is observed, however, in the tropical Pacific, suggesting that previously reported correlations between globally averaged stratification and productivity variability are driven by strong associations in this region. An examination of the long-term changes in our profile data...
Large meta-analyses of terrestrial and aquatic ecosystems suggest that the shape of the productivity–diversity relationship (PDR) is generally either positive or unimodal3–7. For marine phytoplankton, there are less data available but a few large-scale studies also suggest an unimodal PDR response...
Productivity fuels life in the ocean, drives its chemical cycles, and lowers atmospheric carbon dioxide. Nutrient uptake and export interact with circulation to yield distinct ocean regimes.
As knowledge about broadleaf forest responses to O3 in China is insufficient, we selected the equation suggested for broadleaf deciduous forests in Europe (Büker et al., 2015) and diversified the time window depending on the local climate: year–long for tropical and sub–tropical areas ...
normalized productivity in the 1990s. Such inconsistent results undermine the confidence of using prima- ry production estimated fromsatellite ocean color to study the “biolog- ical pump” in the oceans, and suggest that there is difficult work ahead ...
4-5-7 Konan, Minato-ku, Tokyo 108-8477, Japan 2Present address : Louisiana Universities Marine Consortium, 8124 Highway 56, Chauvin, Louisiana 70344, USA ABSTRACT: Appendicularians, pelagic tunicates that are common in world oceans, periodically pro- duce new mucus houses and discard old ones...
In the Antarctic Circumpolar Current (ACC), summer mixed-layer depths are relatively shallower, nutrient concentra- tions are greater, and temperatures are considerably lower than in subtropical and tropical regions, and, not unexpectedly, the phytoplankton assemblage in the ACC is distinct from those...
