Photosynthetic production of organic matter by microscopic oceanic phytoplankton fuels ocean ecosystems
and contributes roughly half of the Earth's net primary production. For 13 years, the Sea-viewing Wide
Field-of-view Sensor (SeaWiFS) mission provided the first consistent, synoptic observations of global ocean
ecosystems. Changes in the surface chlorophyll concentration, the primary...
Plasma membranes isolated from a yeast sterol auxotroph (RD5-R)
grown on 1,5, and 15 pg m1⁻¹ exogenous concentrations of sterol showed
no discontinuity in plots of steady-state fluorescence anisotropy.
Liposomes constructed from phospholipid and sterol extracted from RD5-R
grown on different sterols indicated exogenously supplied sterol
modulated cellular phospholipids such...
Temperature anomalies can identify locations of seeps of groundwater into surface waters.
However, the method’s sensitivity to details such as thermometer burial depth, sediment material, seep
velocity, and surface water current are largely unknown. We report on a series of laboratory flume experiments
in which controlled seeps under variable sediment...

Areas with high species richness have become focal points in the establishment of
marine protected areas, but an understanding of the factors that support this diversity is still
incomplete. In coastal areas, tidal currents—modulated by bathymetry and manifested in variable
speeds—are a dominant physical feature of the environment. However, difficulties...
