Modular Autonomous Biosampler (MAB)- A prototype system for distinct biological size-class sampling and preservation [PDF]

open access: yes, 2012
Presently, there is a community wide deficiency in our ability to collect and preserve multiple size-class biologic samples across a broad spectrum of oceanographic platforms (e.g. AUVs, ROVs, and Ocean Observing System Nodes).

The Arctic Coastal Erosion Model: Overview, Developments, and Calibration at Drew Point, Alaska

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Permafrost coastlines are experiencing significant erosion as polar amplification has enhanced the effects of climate change in the Arctic. Warmer temperatures are increasing thermo‐denudation and more energetic oceans are increasing thermo‐abrasion in unlithified, ice‐bonded permafrost coastlines which comprise at least 40% of the circum ...

First AUV and ROV investigation of seismogenic faults in the Alboran Sea (Western Meditarranean) [PDF]

open access: yes, 2016
In May-June 2015 we carried out the SHAKE cruise on board the RV “Sarmiento de Gamboa” the first in situ investigation using state-of-the-art underwater vehicles, the AUVs “AsterX” and “IdefX” (IFREMER, France) and the ROV “Max Rover” (HCMR, Greece ...

Biodiversity research requires more motors in air, water and on land

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 3, Page 668-682, March 2026.
Abstract Human activities have accelerated species extinctions, driving rapid biodiversity decline. Simultaneously, advancements in Artificial Intelligence (AI) and autonomous systems offer transformative potential for biodiversity research. Uncrewed vehicles—drones (aerial systems) and other robots (ground and underwater platforms)—equipped with high ...

RV Pelagia Cruise 64PE372, 27 Jun - 11 Jul 2013. Flow dynamics and sedimentation in an active submarine channel: a process-product approach [PDF]

open access: yes, 2014
Novel technologies are providing new opportunities to study the structure and dynamics of submarine sediment-gravity flows; these flows are the dominant process for transfer of sediment into the deep ocean, but are very hard to monitor due their ...

Evidence for the Strongest Version of the 4d a-Theorem, via a-Maximization Along RG Flows [PDF]

open access: yes, 2004
In earlier work, we (KI and BW) gave a two line "almost proof" (for supersymmetric RG flows) of the weakest form of the conjectured 4d a-theorem, that a_{IR}

Characteristic Geometry of Keels in Arctic Sea Ice Ridges

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Deformation within and between sea ice floes creates pressure ridges, which compose a considerable volume fraction of the Arctic sea ice cover and complicate sea ice volume measurements. An important parameter for quantifying the ice volume contained in these deformation features is the keel shape.

Star Formation and AGN activity in Galaxies classified using the 1.6 {\mu}m Bump and PAH features at $z = 0.4-2$

open access: yes, 2011
We have studied the star-formation and AGN activity of massive galaxies in the redshift range $z=0.4-2$, which are detected in a deep survey field using the AKARI InfraRed (IR) astronomical satellite and {\em Subaru} telescope toward the North Ecliptic ...
