High Resolution Current & Bathymetry Determined by Nautical X-Band Radar in Shallow Waters [PDF]

open access: yes, 2009
The wave and current monitoring system WaMoS II is a remote sensing system based on a nautical X-Band radar generally used for navigation and ship traffic control.

Comparative Population Genetics of Two Alvinocaridid Shrimp Species in Chemosynthetic Ecosystems of the Western Pacific

open access: yesIntegrative Zoology, EarlyView.
Little is known about the population divergence and gene flow of deep‐sea animals living in disjunct hydrothermal vents and cold seep habitats. Taking advantage of samples collected from multiple cruises across a huge distance of >5000 km, we revealed the differential population divergence pattern and gene flow in two congeneric species of shrimps ...

ALB Evaluation for NOAA charting requirements [PDF]

open access: yes, 2013
The National Oceanic and Atmospheric Administration (NOAA) acquires hydrographic data around the coasts of the US and its territories using in-house surveys and contracting resources. Hydrographic data are primarily collected using sonar systems, while a

Submerged dunes and breakwater embayments mapped using wave inversions of shore-mounted marine X-Band radar data [PDF]

open access: yes, 2010
Surveying very shallow coastal areas, particularly around coastal defences, can be a logistically difficult and time consuming process. A marine-radar based bathymetry mapping technique has been used to remotely map the embayments around a series of ...

Climatic–Anthropogenic Synergy Drives Escalating Minimum Area Requirements and Connectivity‐Protection Mismatch in a Karst‐Endemic Primate

open access: yesIntegrative Zoology, EarlyView.
Climate change and anthropogenic activities drive antagonistic degradation of landscape connectivity for endangered François’ langur (1987–2024), causing 48.8% habitat loss, north‐south fragmentation, and centroid migration (1.2 km/yr). Despite protected areas buffering connectivity, static management fails dynamic priority habitats; we propose ...

High Resolution Mapping in support of UNCLOS Article 76: Seeing the seafloor with new eyes [PDF]

open access: yes, 2007
Since 2003, the Center for Coastal & Ocean Mapping/Joint Hydrographic Center at the University of New Hampshire (UNH) has been conducting multibeam mapping of many U.S.

GLOSSA: A user‐friendly R Shiny application for Bayesian machine learning analysis of marine species distribution

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Species distribution models (SDMs) are one of the most common statistical methods to assess species occupancy and geographic distribution patterns. With the increasing complexity and availability of ecological data in the marine context, many methodological approaches have been developed to support SDM analysis.

Interactive 3-D Visualization: A tool for seafloor navigation, exploration, and engineering [PDF]

open access: yes, 2000
Recent years have seen remarkable advances in sonar technology, positioning capabilities, and computer processing power that have revolutionized the way we image the seafloor.
