Below are listed data sets that Joseph Kennedy has compiled.
Klamath Marsh January Through May Maximum Surface Water Extent, 1985-2021
The U.S. Geological Survey Oregon Water Science Center, in cooperation with The Klamath Tribes initiated a project to understand changes in the surface-water extent of Klamath Marsh, Oregon and changes in groundwater levels within and surrounding the marsh. The initial phase of the study focused on developing datasets needed for future interpretive phases of the investigation. This data release do
Summary of soil field-saturated hydraulic conductivity, hydrophobicity, and preferential-flow measurements and soil laboratory-testing results collected at three sites on the islands of Maui and Hawaii, Hawaii, July 2016-January 2018
The U.S. Geological Survey Pacific Islands Water Science Center and the University of Hawaii at Manoa Department of Geography, in cooperation with the U.S. Department of Interior Pacific Islands Climate Adaptation Science Center initiated a field data-collection program as part of a study to quantify the impacts of drought on water resources and the importance of cloud-water interception in mitiga
Summary of soil field-saturated hydraulic conductivity, hydrophobicity, preferential-flow, and particle-size measurements collected at four research sites on the island of Maui, Hawaii, September 2017-August 2018
The U.S. Geological Survey and the University of Hawaii at Manoa, in cooperation with the County of Maui Department of Water Supply and the State of Hawaii Commission on Water Resource Management, initiated a field data-collection program to provide information for evaluating how infiltration rates and soil hydrophobicity are dependent on plant species type within forested areas on the island of M
Summary of dissolved pesticide concentrations in discrete surface-water samples collected on the islands of Kauai and Oahu between November 21, 2016 and April 29, 2017
The purpose of this release is to make available the quality-assured pesticide-concentration results for 32 discrete water samples that were collected on the islands of Kauaʻi and Oʻahu between November 21, 2016 and April 29, 2017. This webpage includes brief descriptions of the sampling sites, the samples collected, streamflow conditions during sampling, sample-collection and filtration methods,
Cloud water interception in Hawai‘i: Developing capacity to characterize the spatial patterns and effects on water and ecological processes responses in Hawai‘i
Cloud-water interception (CWI) is the process by which fog or cloud water droplets are captured and accumulate on the leaves and branches of plants, some of which drips to the ground. Prior studies in Hawai'i indicate that CWI is highly variable and can contribute substantially to total precipitation. In this study, we monitored CWI and other processes at five mountain field sites on the Islands o
Water-resource management monitoring needs, State of Hawai‘i
In cooperation with the State of Hawai‘i Commission on Water Resource Management and in collaboration with the University of Hawaiʻi Water Resources Research Center, the U.S. Geological Survey developed a water-resource monitoring program—a rainfall, surface-water, and groundwater data-collection program—that is required to meet State needs for water-resource assessment, management, and protection
