Growing pains of a data repository: GRIIDC's evolution from environmental disaster rapid response to promoting FAIR data
(Frontiers in Climate, 2022-08-25)GRIIDC is a multidisciplinary data repository created in the aftermath of the Deepwater Horizon oil spill. Development of the repository occurred even as researchers collected post-spill data, and as a result, the data ... -
Extending Marine Species Distribution Maps Using Non-Traditional Sources
(Pensoft, 2015-04-17)Background Traditional sources of species occurrence data such as peer-reviewed journal articles and museum-curated collections are included in species databases after rigorous review by species experts and evaluators. ... -
Using UAS Hyperspatial RGB Imagery for Identifying Beach Zones along the South Texas Coast
(Multidisciplinary Digital Publishing Institute, 2017-02-15)Shoreline information is fundamental for understanding coastal dynamics and for implementing environmental policy. The analysis of shoreline variability usually uses a group of shoreline indicators visibly discernible in ... -
Estuarine Suspended Sediment Dynamics: Observations Derived from over a Decade of Satellite Data
(Frontiers in Marine Science, 2017-12-20)Suspended sediment dynamics of Corpus Christi Bay, Texas, USA, a shallow-water wind-driven estuary, were investigated by combining field and satellite measurements of total suspended solids (TSS). An algorithm was developed ... -
Unsupervised Clustering Method for Complexity Reduction of Terrestrial Lidar Data in Marshes
(Multidisciplinary Digital Publishing Institute, 2018-01-18)Accurate characterization of marsh elevation and landcover evolution is important for coastal management and conservation. This research proposes a novel unsupervised clustering method specifically developed for segmenting ... -
Ensemble Neural Networks for Modeling DEM Error
(Multidisciplinary Digital Publishing Institute, 2019-10-09)Digital elevation models (DEMs) have become ubiquitous and remarkably effective in the field of earth sciences as a tool to characterize surface topography. All DEMs have a degree of inherent error and uncertainty that is ... -
Unsupervised Clustering of Multi-Perspective 3D Point Cloud Data in Marshes: A Case Study
(Multidisciplinary Digital Publishing Institute, 2019-11-19)Dense three-dimensional (3D) point cloud data sets generated by Terrestrial Laser Scanning (TLS) and Unmanned Aircraft System based Structure-from-Motion (UAS-SfM) photogrammetry have different characteristics and provide ... -
Meeting Regional, Coastal and Ocean User Needs With Tailored Data Products: A Stakeholder-Driven Process
(Frontiers in Marine Science, 2019-06-07)New coastal and ocean observing stations and instruments deployed across the globe are providing increasing amounts of meteorological, biological, and oceanographic data. While these developments are essential for the ... -
Using Lidar Data to Assess the Relationship Between Beach Geomorphology and Kemp’s Ridley (Lepidochelys kempii) Nest Site Selection Along Padre Island, TX, United States
(Frontiers in Marine Science, 2020-04-08)The Kemp’s ridley sea turtle (Lepidochelys kempii) is the most endangered sea turtle species in the world, largely due to the limited geographic range of its nesting habitat. There has been limited research regarding the ...
