This shapefile contains cumulative fish habitat condition index (HCI) scores as well as specific disturbance indices for local and network catchments of Southeast Alaska. Catchments were created in support of Jared Ross's Master’s thesis. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) broadly representative of conditions in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among local catchment units.

A visual impact evaluation method specifically designed to assess landscape alteration as a result of surface mining and quarrying would represent a fundamental aid for both those involved in the early stages of mine planning and design (mining companies) and those in charge of controlling and verifying environmental impacts (government authorities). This research is based on implementation of the visual impact indicator Lvi, which takes into account two parameters among those physically measurable: the extent of visible alteration in the landscape and the chromatic contrast between bare rock and the surrounding environment. Both parameters can be quantified by processing one or more digital images taken from the...

Fish collections made at Buck Island Reef National Monument with the ichthyocide rotenone in 2001 at 58 stations followed by 10 days each in April 2011 and January 2012 surveying poorly sampled shoreline habitats with rotenone and clove oil and inland streams with seine.

This shapefile contains cumulative fish habitat condition index (HCI) scores and specific disturbance indices for local and network stream catchments as well as the downstream main channel catchment of perennial and intermittent streams reaches of the five main island of Hawai'i. In this dataset indices are linked to the Hawaii Fish Habitat Partnership (HFHP) stream layer (Tingley et al. in prep) which is a modified version of the 1:24,000 National Hydrography Dataset. It includes 11,436 intermittent and perennial stream reaches across the five main Hawaiian Islands (Hawai’i, Maui, Moloka’i, O’ahu, Kaua’i). Catchment attributes are available for both local catchments (defined as the land area draining directly to...

MARIS is an internet-based information sharing network that allows multiple states to provide a common set of variables via a single web interface. MARIS is not a “dataset” but rather links specific content of multiple states’ datasets. MARIS does not capture all of the information from a state’s aquatic dataset – only a subset of data collected as part of aquatic species sampling surveys. The MARIS structure was developed by a consortium of state fish and wildlife agencies and implemented through contracts with various universities. In the past, federal agency partners have provided the core funding for developing and implementing MARIS as well as broad guidance on the content of the system. In 2014 the U.S. Geological...
