Facilitating macrosystem biology with organismal‐scale airborne remote sensing: Challenges and opportunities

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Emergent ecosystem properties, such as population and trait distributions, biodiversity and energy and water fluxes, occur because of the dynamic interactions of individuals in their environment.

Reviewing seas of data: Integrating image‐based bio‐logging and artificial intelligence to enhance marine conservation

Methods in Ecology and Evolution, EarlyView.
Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...

Investigating Remote Warfare as the Radical Undoing of Life: The Compounding Civilian Harm Effects of US‐Led Coalition Bombings in Iraq

Antipode, EarlyView.
Abstract The increased reliance on remote warfare by US‐led military coalitions presents us with questions of “what war is” and “how to know about war” in the 21st century. In this article we substantiate calls for an embodied epistemology of war by introducing a transdisciplinary research agenda to investigate the temporal and spatial civilian harm ...

High-Resolution Sonars: What Resolution Do We Need for Target Recognition?

EURASIP Journal on Advances in Signal Processing, 2010
Target recognition in sonar imagery has long been an active research area in the maritime domain, especially in the mine-counter measure context. Recently it has received even more attention as new sensors with increased resolution have been developed ...

Combining morphological and molecular data to study past foraminiferal communities from a temperate coastal sediment core

Boreas, EarlyView.
This paper presents the results of a dual approach for assessing fossil benthic foraminiferal communities using both traditional morphology‐based analyses and sedimentary ancient DNA (sedaDNA) metabarcoding. The main objectives are to test the feasibility of sedaDNA analyses to assess foraminiferal biodiversity in temperate shelf sediments (Le Croisic,

Adaptive Coverage Path Planning for Underwater Sonar Scans in Environments with Changing Currents

Journal of Marine Science and Engineering
This article considers underwater sonar scans that utilize a sonar-equipped Autonomous Marine Ship (AMS). The AMS finds an underwater object by towing a tow fish, having active sonars for imaging the sea bottom.

Benthic habitat mapping in the Olympic Coast National Marine Sanctuary: Classification of side scan sonar data from survey HMPR-108-2002-01: Version I [PDF]

, 2006
In September 2002, side scan sonar was used to image a portion of the sea floor in the northern OCNMS and was mosaiced at 1-meter pixel resolution using 100 kHz data collected at 300-meter range scale.
