The ocean modulates the response of Earth’s climate to forcing by transporting and storing large quantities of heat and carbon. Because the ocean’s transport pathways are dependent upon the position of the continents, it is thought that past changes in ocean gateways may have had an outsize impact on Earth’s climate evolution.

Microbes play a major role in the ocean carbon cycle. Understanding their metabolism will be critical for improving our capacity to predict ocean processes as global temperatures rise and the climate changes. Theory predicts that respiration is more sensitive to increases in temperature than photosynthesis and that cell size tends to decrease...

Glaciers have covered ~10-30 % of land surface over the past 100,000 years and are sensitive barometers of climatic change, yet are rarely considering in conceptual models of global biogeochemical cycles.

Oysters are temperate reef-building species that have undergone substantial population declines world-wide. The eastern oyster (Crassostrea virginica) is a keystone species in the Chesapeake Bay, which once was the largest oyster fishery in the world.

Abstract: 

Heinrich events were quasiperiodic episodes of ice-rafted detritus deposition in the North Atlantic during the last glacial period, associated with enhanced iceberg discharge from the Hudson Strait Ice Stream.

Echinoderm diseases include some of the most geographically widespread and ecologically significant phenomena ever recorded in coastal marine habitats. Loss of echinoderm predators and herbivores due to these conditions has led to persistent shifts in benthic community structures.

Soil is a nexus of nitrogen (N) transformations that influence ecosystem productivity, climate, and air and water quality. Yet, resolving microbial, plant, and environmental processes driving N cycling is challenged by the interacting processes, overlapping substrates, and dynamic spatiotemporal features.

There are 524 abandoned uranium mines on the Navajo Nation from the Cold War. Many families had relatives that were part of the past uranium mining activities that long passed on. Nowadays, only one uranium mine was remediated by the United States Environmental Agency Region 9.
