Monitoring Change in Great Salt Lake

Great Salt Lake Selenium Standard

The Great Salt Lake ecosystem is widely recognized to be unique and to have very high environmental and commercial value. Great Salt Lake is recognized regionally, nationally, and hemispherically for its extensive wetlands, and its tremendous and often unparalleled values to migratory birds. These values are derived from the lake’s unique physical features, including its immense size, dynamic w...

Crustal loading near Great Salt Lake, Utah

[1] Two sites of the BARGEN GPS network are located 30 km south of Great Salt Lake (GSL). Lake-level records since mid-1996 indicate seasonal water elevation variations of 0.3 m amplitude superimposed on a roughly ‘‘decadal’’ feature of amplitude 0.6 m. Using an elastic Green’s function and a simplified load geometry for GSL, we calculate that these variations translate into radial crustal load...

Great Salt Lake Past and Present: Elevation and Salinity Changes to Utah's Great Salt Lake from Railroad Causeway Alterations

Selenium mass balance in the Great Salt Lake, Utah.

A mass balance for Se in the south arm of the Great Salt Lake was developed for September 2006 to August 2007 of monitoring for Se loads and removal flows. The combined removal flows (sedimentation and volatilization) totaled to a geometric mean value of 2079 kg Se/yr, with the estimated low value being 1255 kg Se/yr, and an estimated high value of 3143 kg Se/yr at the 68% confidence level. The...

Conceptual Model for Selenium Cycling in the Great Salt Lake

This document describes a conceptual model for selenium cycling in the Great Salt Lake. The document consists of four parts: A) Introduction to the problem & Overview (page 1) B) The framework of the model and underlying assumptions (page 7) C) Visual depiction of conceptual model (page 17) D) Relevant references supporting the model framework (page 22) During the Fall of 2005 a panel of nation...
