Time-Dependent Salinity and Temperature Structure of the Columbia River Salt Wedge and River Plume: Analysis of Conductivity/Temperature/Depth Profiles from Sensors Attached to Pinnipeds and Diving Waterbirds

Abstract

The overall objective of this study is to assess the efficiency and effectiveness of using sensors attached to pinnipeds and waterbirds to make water-column measurements to quantify variability in hydrographic properties and to map variations in bathymetry in environments such as estuaries and the coastal ocean. Marine mammals and waterbirds have been used in the past to document water column properties in the ocean (Boehlert et al., 2001; Lydersen et al., 2002; Daunt et al., 2003; McMahon et al., 2005; Charassin et al., 2008; Costa et al., 2008; Simmons et al., 2009; Boehme et al., 2009; Costa et al., 2010; Padman et al., 2010). In this study, we utilize tagged marine animals in regions where water properties exhibit a high degree of variability, both in space and time, such as estuaries ands the inner continental shelf.
