Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

The First World War at Sea: Death, Commemoration and Cultural Remembrance

open access: yesHistory, EarlyView.
Abstract Despite the ever‐increasing body of work devoted to war memorials, national days of remembrance and the commemoration of the First World War in Britain, academic focus remains firmly on the commemoration of the First World War on land. Yet, while the number of people who died at sea paled in comparison to their counterparts on the battlefield ...

Investigating the Susceptibility to Failure of a Rock Cliff by Integrating Structure-from-Motion Analysis and 3D Geomechanical Modelling

open access: yesRemote Sensing, 2020
Multi-temporal UAV and digital photo surveys have been acquired between 2017 and 2020 on a coastal cliff in soft rocks in South-Eastern Italy for hazard assessment and the corresponding point clouds have been processed and compared.

The Wind of Change: Mapping Wind Energy Growth and Multi‐Species Vulnerability in Sardinia, Mediterranean

open access: yesAnimal Conservation, EarlyView.
The rapid expansion of wind energy across the Mediterranean region calls for more advanced tools to assess and mitigate its impacts on biodiversity. In this study, we present an innovative approach combining 13‐year satellite imagery analysis and ecological modelling, to assess the spatiotemporal overlap between wind energy development and habitat ...

What can lithics tell us about hominin technology's ‘primordial soup’? An origin of stone knapping via the emulation of Mother Nature

open access: yesArchaeometry, EarlyView.
Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages): a review

open access: yesBoreas, EarlyView.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

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]

open access: yes, 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.

Aeolianite and barrier dune construction spanning the last two glacial-interglacial cycles from the southern Cape coast, South Africa [PDF]

open access: yes, 2004
The southern Cape region of South Africa has extensive coastal aeolianites and barrier dunes. Whilst previously reported, limited knowledge of their age has precluded an understanding of their relationship with the climatic and sea-level fluctuations ...
