Groundwater Hydrogeolgy And Hydrochemistry Of Karst Springs In The Eastern Peninsula Of Fort Hood Military Installation, William Scribner Welles
Groundwater Hydrogeolgy And Hydrochemistry Of Karst Springs In The Eastern Peninsula Of Fort Hood Military Installation, William Scribner Welles
Electronic Theses and Dissertations
The eastern peninsula of Fort Hood Military Installation is underlain by a complex karst spring network. These springs are a primary water source in a protected habitat for endangered songbirds, which has only recently begun to be fully investigated. These Fredericksburg Group springs express both epigenetic and hypogenetic karst signatures. The study area is part of a paleo reef trend, a hydraulically disconnected segment of the northern section of the Edwards Aquifer. This study utilized standard ion index values, repeated measures, and principal component analyses on the chemical profiles of six perennial springs to classify spring water sources and their …
Functions Of Ecosystems: Stream Metabolism As An Efficient And Effective Means To Gage The Health And Understand The Interworking Of Urban Streams In A Watershed Of Rock Island, Il, Ryan Johnson, Dr. Kevin Geedey
Functions Of Ecosystems: Stream Metabolism As An Efficient And Effective Means To Gage The Health And Understand The Interworking Of Urban Streams In A Watershed Of Rock Island, Il, Ryan Johnson, Dr. Kevin Geedey
Celebration of Learning
Stream metabolism is a critical functional measure of stream health that integrates physical parameters like slope and discharge, with ecosystem functions like photosynthesis and respiration. Stream metabolism is widely studied; however, urban stream metabolism remains poorly understood. Stream metabolism was measured for five streams ranging from 1st to 5th orders from October 11th to October 18th 2017 and four streams ranging from 1st to 4th order from October 22nd to 25th 2017 located within an approximately 9.3 square kilometer watershed of Rock Island, IL that has an urban to suburban type of …
Community Members Of All Ages Work Together To Reveal The Dynamic Nature Of Liberty Bay, Lauren Kemper, Markie Rodgers, Catherine Somerville, Melissa O'Brien, Charles Kleinwort, Sylvia Yang

Salish Sea Ecosystem Conference
At the SEA Discovery Center, we have begun a community citizen science project to monitor Liberty Bay, to gain a deeper sense of understanding and inspire stewardship of the local marine environment. As a public aquarium and marine science center serving the communities of the Kitsap Peninsula region, the SEA Discovery Center has the opportunity to engage the community in environmental science that no one person could do alone. Elementary students, college interns, volunteers, and visitors from the community are mentored by SEA Discovery Center staff to measure abiotic (seawater temperature, salinity, dissolved oxygen) and biotic (phytoplankton and zooplankton abundance …
Citizen Science Demonstrates Need And Importance At Whatcom County Beaches, Natalie Lord, Olivia Latimer, Eleanor Hines
Citizen Science Demonstrates Need And Importance At Whatcom County Beaches, Natalie Lord, Olivia Latimer, Eleanor Hines
Salish Sea Ecosystem Conference
The Blue Water Task Force (BWTF) is a volunteer-run, water testing, education and advocacy program of the Surfrider Foundation. The purpose is to engage citizen scientists in monitoring pollution and provide pollution prevention awareness at popular marine recreation areas. The Northwest Straits (NWS) Chapter samples monthly at six sites in the Bellingham Bay area for enterococcus, an indicator bacteria. Whatcom County often has beach closures throughout the summer due to poor water quality that does not meet the federal standards for recreation. One such location is Little Squalicum Beach, which has a permanent swimming advisory due to high bacteria levels. …
Extending Observations Further: Using Historic Biogeochemical Data To Understand Trends In Puget Sound, Ben Larson, Stephanie Jaeger, Wendy Eash-Loucks, Kimberle Stark, Bruce Nairn
Extending Observations Further: Using Historic Biogeochemical Data To Understand Trends In Puget Sound, Ben Larson, Stephanie Jaeger, Wendy Eash-Loucks, Kimberle Stark, Bruce Nairn
Salish Sea Ecosystem Conference
Fluctuations in Puget Sound water quality reflect a combination of natural variability and anthropogenic influence. Predictions of how future changes will unfold requires an understanding of the complex interplay between these factors. Recent and ongoing measurement of water quality parameters allow a thorough assessment of variability over short time scales, but understanding changes over longer (e.g., decadal) timescales is critical for forecasting future changes. Examining long term trends requires the use of historical data, however, measurements that pre-date modern monitoring programs can be scarce, and the detection limits are often higher than newer analytical techniques. Here, we will consider several …
