Altimeter sea surface height (SSH) fields are analyzed to define and discuss the seasonal circulation
over the wide continental shelf in the SW Atlantic Ocean (27°–43°S) during 2001–2012. Seasonal variability
is low south of the Rio de la Plata (RdlP), where winds and currents remain equatorward for most of
the...

Satellite-derived sea surface salinity (SSS) data from Aquarius and SMOS are used to study the
shelf-open ocean exchanges in the western South Atlantic near 35°S. Away from the tropics, these
exchanges cause the largest SSS variability throughout the South Atlantic. The data reveal a well-defined
seasonal pattern of SSS during...

Intraspecific life history attributes of growth, survival, and reproduction can vary in
response to changes in the physical environment. These changes can induce a cascading effect
across trophic levels. In marine systems, shifts in ocean conditions such as warm and cold phases
of ENSO can change primary production in benthic...

Family influence in the home environment has been linked to children’s nutrition and physical activity behaviors. However few tools exist to identify family level behaviors and families’ readiness to change those behaviors, particularly for populations at high risk for obesity such as Hispanics. This study summarizes the relationships of similar...

Time-series observations are critical to understand the structure, function, and dynamics of marine ecosystems. The Hawaii Ocean Time-series program has maintained near-monthly sampling at Station ALOHA (22°45′N, 158°00′W) in the oligotrophic North Pacific Subtropical Gyre (NPSG) since 1988 and has identified ecosystem variability over seasonal to interannual timescales. To further...

Mountain environments are currently among the ecosystems least invaded by non-native
species; however, mountains are increasingly under threat of non-native plant invasion.
The slow pace of exotic plant invasions in mountain ecosystems is likely due to a combination
of low anthropogenic disturbances, low propagule supply, and extreme/steep environmental
gradients. The...
