Conterminous United States Remote Sensing Phenology Metrics Database Conterminous United States Remote Sensing Phenology Metrics Database
Phenological dynamics of terrestrial ecosystems reflect the response of the Earth's vegetation canopy to changes in climate and hydrology and are thus important to monitor operationally. Researchers at the U.S. Geological Survey (USGS), Earth Resources Observation and Science (EROS) Center have developed methods for documenting the seasonal dynamics of vegetation in an operational...
Surficial and subsurface grain-size data for the Siletz River, Oregon, 2017-18 Surficial and subsurface grain-size data for the Siletz River, Oregon, 2017-18
The Siletz River Basin encompasses 970 square kilometers of western Oregon and drains to the Pacific Ocean. In cooperation with the Confederated Tribes of the Siletz Indians of Oregon (CTSI), the U.S. Geological Survey is evaluating how streamflow and bedload sediment conditions may influence mainstem spawning habitats for spring Chinook Salmon (Oncorhynchus tshawytschya) and Pacific...

Laboratory Assessment of Colloidal Borescope and Heat-Pulse Flowmeters in Measuring Horizontal Flow in Fractured-Rock Simulators Laboratory Assessment of Colloidal Borescope and Heat-Pulse Flowmeters in Measuring Horizontal Flow in Fractured-Rock Simulators
The U.S. Geological Survey (USGS), at the request of the U.S. Army Environmental Command (USAEC), evaluated the capabilities of two borehole technologies to measure horizontal groundwater velocity and direction of flow in a parallel-plate fractured-rock simulator. A colloidal borescope flowmeter (HB) and a heat-pulse flowmeter (HH) were deployed in 4-inch and 6-inch inner-diameter...
Sea Otter Aerial Survey Data from the Outer Kenai Peninsula, Alaska, 2019 Sea Otter Aerial Survey Data from the Outer Kenai Peninsula, Alaska, 2019
This dataset consists of three tables related to abundance and distribution of northern sea otters (Enhydra lutris kenyoni) near the outer Kenai Peninsula, Alaska, based on data collected during a series of population-wide aerial surveys in June 2019. The dataset consists of: (1) sea otter counts along strip transects, (2) sea otter counts in Intensive Search Unit (ISU) within the...
