Hydrothermal fluid circulation through the sediment of Crater Lake, Oregon: Pore water and heat flow constraints

Creator:

Wheat, C. Geoffrey, McManus, James, Dymond, Jack, Collier, Robert W., and Whiticar, Michael

Abstract:

We present evidence for pore water flow through the sediment of Crater Lake, Oregon based on systematic variations in pore water chemical compositions and thermal gradients. Pore water was extracted from sediment by centrifugation and diffusive exchange using a gravity corer deployed from a surface vessel and a box corer...

Spatial and temporal distribution of dissolved oxygen in Crater Lake, Oregon

Creator:

McManus, James, Collier, Robert W., Dymond, Jack, Wheat, C. Geoffrey, and Larson, Gary L.

Abstract:

Small temporal and spatial variations in the distribution of dissolved oxygen in Crater Lake, Oregon, are used to estimate the mean age of the lake’s deep water, the flux of labile organic carbon to the deep lake, and the influence of hydrothermal activity on the concentration of dissolved oxygen within...
