Tidally varying methane (CH4) concentrations in estuaries may arise from physical advection and by chemical effects tied to varying exposure to salinity. An investigation of spatial and temporal variability in water-column CH4 was conducted in the lo

Observations of enhanced volcanic frequency during the last deglaciation have led to the hypothesis that ice unloading in glaciated volcanic terrains can promote volcanism through decompression melting in the shallow mantle or a reduction in crustal

Examining fluxes of biogeochemical constituents at the mouth of an estuary is necessary for assessing the modification of terrigenous-source materials in the estuary prior to reaching the ocean. In many rivers and estuaries, including the Columbia Ri

Summertime carbon, nitrogen, and biogenic silica export was examined using 234Th:238U disequilibria combined with free floating sediment traps and fine scale water column sampling with in situ pumps (ISP) within the Eastern Tropical North Pacific and

A combined culture and field study was conducted in order to (1) more firmly identify the physiological controls on hydrogen isotopic composition of C37 alkenones produced by open-ocean coccolithophores and (2) determine the degree to which these con
