A vision for America's Great Watershed Report Card

Heath Kelsey, Caroline Donovan, Brianne Walsh, Jonathan Kellogg, Bill Dennison, Alexandra Fries ·
27 September 2012

Report cards can be part of a tiered approach to communicating results with varying technical detail. Our vision for this report card framework is based on goals identified in America’s Great Watershed Initiative and derived from principles of Integrated River Basin Management. The framework includes balanced information from Social, Economic, and Environmental sectors, and is intended to be transparent and clear.

2011 Chesapeake Bay Report Card (Page 1)

2011 Chesapeake Bay Report Card

Bill Dennison, Caroline Donovan, Jonathan Kellogg, Alexandra Fries ·
17 April 2012

This report card provides a transparent, timely, and geographically detailed assessment of Chesapeake Bay. The overall health of Chesapeake Bay, determined using water quality and biotic indicators, declined slightly in 2011. The overall grade of D+ was a decrease for the second year in a row, down from a C- in 2010. Only two reporting regions, the Patapsco and Back Rivers, and the Lower Western Shore (MD), had improved grades in 2011.

Bacteria sampling and data analysis protocol addendum for Mid-Atlantic tidal tributary indicators (Page 1)

Bacteria sampling and data analysis protocol addendum for Mid-Atlantic tidal tributary indicators

Wicks EC, Kelsey RH, Fries AS, Kellogg JP ·
13 January 2012

This document provides guidelines for the successful production of tidal ecosystem health report cards. Specifically, this document serves as an addendum to the Sampling and data analysis protocols for Mid-Atlantic tidal tributary indicators which develops a clear and consistent protocol for the identification, collection, and analysis of the indicator of bacteria.

A hydrographic transient above the Salty Dawg hydrothermal field, Endeavour segment, Juan de Fuca Ridge

Kellogg JP and McDuff RE ·

During systematic repeat hydrography cruises to the Endeavour segment of the Juan de Fuca Ridge in the summers of 2004, 2005, and 2006, we encountered a transient increase in the water column heat content above the Salty Dawg hydrothermal field. First observed in July 2005 and mapped in greater detail in August 2005, this feature was not a typical event or megaplume since potential temperature anomalies were continuously elevated from the plume top to the seafloor.

A descriptive analysis of temporal and spatial patterns of variability in Puget Sound oceanographic properties

Moore SK, Mantua NJ, Newton JA, Kawase M, Warner MJ, and Kellogg JP ·

Temporal and spatial patterns of variability in Puget Sound's oceanographic properties are determined using continuous vertical profile data from two long-term monitoring programs; monthly observations at 16 stations from 1993 to 2002, and biannual observations at 40 stations from 1998 to 2003. Climatological monthly means of temperature, salinity, and density reveal strong seasonal patterns.

Local and large-scale climate forcing of Puget Sound oceanographic properties on seasonal to interdecadal timescales

Moore SK, Mantua NJ, Kellogg JP, and Newton JA ·

The influence of climate on Puget Sound oceanographic properties is investigated on seasonal to interannual timescales using continuous profile data at 16 stations from 1993 to 2002 and records of sea surface temperature (SST) and sea surface salinity (SSS) from 1951 to 2002. Principal components analyses of profile data identify indices representing 42%, 58%, and 56% of the total variability at depth-station combinations for temperature, salinity, and density, respectively…
