Dirnberger, J. M. and J. Weinberger. 2005. Influences of lake level changes on reservoir water clarity in Allatoona Lake, Georgia. Lake and Reserv. Manage. Vol. 21(1):24-29. In Allatoona Lake (Georgia USA), secchi transparency (measured every 2 to 4 weeks during a Phase I U.S. EPA Clean Lakes Study) was typically 5to 8fold greater in summer than late autumn and winter. The intensity of storms i...

As the global climate changes, the higher latitudes are seen to be warming significantly faster. It is likely that the Arctic biome will experience considerable shifts in ice melt season length, leading to changes in photoirradiance and in the freshwater inputs to the marine environment. The exchange of nutrients between Arctic surface and deep waters and their cycling throughout the water colu...

We investigated the distribution, photoproduction, microbial uptake, and air–sea exchange of carbon monoxide (CO), a key photoproduct of chromophoric dissolved organic matter (CDOM), in open waters of the southeastern Beaufort Sea in autumn 2003 and spring 2004. Diurnal cycles of surface water CO concentration ([CO]) occurred in autumn but not in spring. In both seasons [CO] was well above air-...

Seasonal and year-to-year time evolution of the thermal structure, including the heat content change in the upper water column and its relationship with the surface net heat fluxes, have been studied at five locations in the central Mediterranean Sea. The study is based on temperature profiles collected during XBT surveys (eXpendable BathyThermograph) carried out on ships of opportunity, in the...

The comparison of modern hydrophysical conditions in the Black Sea with previously analyzed period 1903—1982 was carried out based on materials recently created (1991—2020) climate array average monthly thermohaline characteristics waters. dynamic processes upper 150-meter layer (halocline) evaluated analysis climatic vertical distribution depth maximum water salinity gradient, which is interpr...
