Mountains provide critical services for human society and important habitats for diverse forms of life. They are also changing rapidly: temperatures are rising, leading to shifts in the timing of snowmelt, the amount of water flowing downstream, and the length of the snow-free growing season. While more than one-sixth of the world’s population lives in… Read more »

9632763 Smith This proposal continues, for a second six year period, the Palmer Long-Term Ecological Research program which focuses on the marine ecosystem in the western Antarctic Peninsula region. A central tenet of this research is that the annual advance and retreat of sea ice is a major physical determinant of spatial and temporal changes… Read more »

The Palmer, Antarctica, Long-Term Ecological Research Project (PAL) seeks to understand the structure and function of the Western Antarctic Peninsula’s marine and terrestrial ecosystems in the context of seasonal-to-interannual atmospheric and sea ice dynamics, as well as long-term climate change. The PAL measurement system (or grid) is designed to study marine and terrestrial food webs… Read more »

Since 1990, Palmer LTER (PAL) research has been guided by the hypothesis that variability in the polar marine ecosystem is mechanistically coupled to changes in the annual advance, retreat and spatial extent of sea ice. Since that time, the hypothesis has been modified to incorporate climate migration, i.e. the displacement of a cold, dry polar… Read more »

The Palmer Antarctica LTER (Long Term Ecological Research) site has been in operation since 1990. The goal of all the LTER sites is to conduct policy-relevant research on ecological questions that require tens of years of data, and cover large geographical areas. For the Palmer Antarctica LTER, the questions are centered around how the marine… Read more »

The goal of all LTER sites is to conduct policy-relevant ecosystem research for questions that require tens of years of data and cover large geographical areas. The Palmer Antarctica Long Term Ecological Research (PAL-LTER) site has been in operation since 1990 and has been studying how the marine ecosystem west of the Antarctica Peninsula (WAP)… Read more »

Climate change is predicted to have a significant impact on marine food webs. This is especially true for polar systems where ocean biology and chemistry are strongly tied to the presence or absence of sea ice. The Palmer Long Term Ecological Research program is focused on developing a fundamental understanding of the ecology of the… Read more »

Nutrient movement into estuaries and the resulting effects on primary productivity, the depletion of oxygen, habitat structure, and trophic changes in coastal waters have dominated estuarine research for decades. Another, and neglected, linkage between land and coastal waters is the input of dissolved and particulate organic carbon and organic nitrogen. Organic nitrogen inputs are frequently… Read more »
