Sediment microbial communities in long‐term wetland restorations within the Prairie Pothole Region of the United States

Restoration Ecology, EarlyView.
Hydrologic wetland restoration in the Prairie Pothole Region is a common management practice to facilitate habitat and ecosystem recovery after degradation or drainage. Little is known about the recovery of sediment microbial communities relative to other organisms, such as vegetation, fish, and macroinvertebrates, even though they are critical for ...

An Algorithm for Sound Velocity Error Correction Using GA-SVR Considering the Distortion Characteristics of Seabed Topography Measured by Multibeam Sonar Mounted on Autonomous Underwater Vehicle

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Aiming to address the problem that autonomous underwater vehicle (AUV) with multibeam echo sounder system (MBES) for underwater topographic survey cannot autonomously obtain the sound velocity of the acoustic path to correct bathymetric data, this ...

Artifex Ars Cartographica: Collaboration Between Portuguese Painters and Cartographers in the Fifteenth and Sixteenth Centuries

Renaissance Studies, EarlyView.
ABSTRACT During the fifteenth and sixteenth centuries, there was no statutory difference between cartography, drawing and painting. These activities were performed then by craftsmen who were part of a vast group under the umbrella of ‘mechanical arts’ and fell under the ‘artifex’ category. Artifex were experts in any particular art, whether a craftsman,

Future directions in hydrography using satellite-derived bathymetry [PDF]

, 2013
Satellite remote sensing provides useful reconnaissance tool for mapping near-shore bathymetry, characterizing a coastal area and monitoring any seafloor changes that may have occurred since the last hydrographic survey of the area.

Spatiotemporal Forecasting of Mediterranean Blue Mussel Biofouling Settlement to Inform Aquaculture Management

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
Mediterranean blue mussel (Mytilus galloprovincialis) settlement significantly influences aquaculture productivity and biofouling management in New Zealand's coastal waters due to its rapid colonization of farming infrastructure and its competitive interactions with cultivated species.

A Crossover Adjustment Method Considering the Beam Incident Angle for a Multibeam Bathymetric Survey Based on USV Swarms

Journal of Marine Science and Engineering
Multibeam echosounder systems (MBESs) are widely used in unmanned surface vehicle swarms (USVs) to perform various marine bathymetry surveys because of their excellent performance. To address the challenges of systematic error superposition and edge beam

Mesoscale and Submesoscale Variability in the Indian Ocean

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Material transport and air‐sea coupling dynamics associated with monsoon‐related mesoscale and submesoscale processes in the Indian Ocean significantly modulate biogeochemical cycles, the large‐scale energy balance, and both regional and global climate change.

Method for Delineating the Formula Limit of the Continental Shelf under the Maximum Area Principle Constraint

Journal of Marine Science and Engineering
In current practices of determining continental shelf area, the measured sediment thickness data do not effectively reflect the distribution of sediments across the area due to its dispersed nature.
