TL;DR: The seasonal variability of surface chlorophyll in the northern Humboldt Current System is studied using satellite data, in situ observations and model simulations as mentioned in this paper, and the results suggest that seasonal variability in the mixed layer depth is the main controlling factor of the seasonality.
TL;DR: This study evaluated three water supply reservoirs with bottom-release (hypolimnion) outlet structures in Arizona and found that in-reservoir reactions were more important in changing MIB concentrations than conservative hydraulic "flushing" of the reservoir.
TL;DR: In this paper, a multi-year continuous observations of velocity and salinity in the Chesapeake Bay indicate that wind-induced destratification occurs frequently from early fall through midspring over large areas of the estuary, suggesting a mechanism involving the generation of dynamic instability across the pycnocline.
Abstract: Multiyear continuous observations of velocity and salinity in the Chesapeake Bay indicate that wind-induced destratification occurs frequently from early fall through midspring over large areas of the estuary. Storm-driven breakdown of summer stratification was observed to occur near the autumnal equinox in two separate years. Surface cooling plays an important, though secondary, role in the fall destratification by reducing the vertical temperature gradient in the days prior to the mixing event. Large internal velocity shear precedes mixing events, suggesting a mechanism involving the generation of dynamic instability across the pycnocline. Destratification is shown to fundamentally alter the response of the velocity field to subsequent wind forcing; in stratified conditions, response is depth-dependent, while after mixing a depth-independent response is observed.
TL;DR: In this paper, a simple conceptual model of phytoplankton dynamics accounts for instances of the temporal succession of stratification and destratification of the water column, observed on a wide range of scales, and it may be applied to such structures as fronts and intermittent upwellings.
TL;DR: Stratification and a large area of anoxic sediments persisted despite pump operation in the summers of 2004 and 2005, andTransparencies increased substantially after the winter storms in 2005 and thermal stability was shown to be strongly dependent upon lake level.
