Machine learning for improved size estimation of complex marine particles from noisy holographic images

Zonghua Liu, Marika Takeuchi, Yéssica Contreras, Thangavel Thevar et autres

Size estimation of particles and plankton is key to understanding energy flows in the marine ecosystem. A useful tool to determine particle and plankton size - besides abundance and taxonomy - is in situ imaging, with digital holography being particularly useful for …

Sheared turbulent flows and wake dynamics of an idled floating tidal turbine

Lilian Lieber, Shaun Fraser, Daniel Coles, W. Alex M. Nimmo‐Smith

Ocean energy extraction is on the rise. While tides are the most predictable amongst marine renewable resources, turbulent and complex flows still challenge reliable tidal stream energy extraction and there is also uncertainty in how devices change the natural environment. To ensure …

Validation of High-resolution ADCP Measurements of TKE Dissipation Influenced by Waves

Elias Marchetti, T. Culverhouse, Thomas Comerford, W. Alex M. Nimmo‐Smith

This study evaluates the capability of the new Origin 600 (Sonardyne) high-resolution five-beam Acoustic Doppler Current Profiler (ADCP) to measure turbulence in shallow coastal waters influenced by surface waves. Evaluation was done through comparison between bedframe-mounted, upwards-facing ADCP data and a free-falling …

Selective foraging behavior of seabirds in small‐scale slicks

Lilian Lieber, Cynthia Füchtencordsjürgen, Rebecca L. Hilder, Paula J. Revering et autres

Abstract Marine predator foraging opportunities are often driven by dynamic physical processes enhancing prey accessibility. Surface slicks are ubiquitous yet ephemeral ocean features where convergent flows accumulate flotsam, concentrating marine organisms and pollutants. Slicks can manifest on the sea surface as meandering …

To fly or not to fly? Comparing vantage point and uncrewed aerial vehicle surveys for assessments of seabird abundance and fine-scale distribution

Melissa M. Costagliola-Ray, Lilian Lieber, W. Alex M. Nimmo‐Smith, Elizabeth A. Masden et autres

Marine renewable energy developments (e.g. offshore wind, wave, and tidal) are an increasing feature within the marine environment. It is therefore important to understand the potential impacts of such developments on seabirds that use these environments. Land-based vantage point (VP) surveys are …

Total Water Column Analysis Shows the Importance of a Single Species in Subsurface Chlorophyll Maximum Thin Layers in Stratified Waters

Michelle L. Barnett, Alan E.S. Kemp, W. Alex M. Nimmo‐Smith, Duncan A. Purdie

Marine phytoplankton form the base of marine food webs and are the driving force of the marine carbon cycle, so understanding the dynamics of their blooms is critical. While near-surface marine productivity (<10 m water depths) is extensively documented, that of the …

Data from: Selective foraging behaviour of seabirds in small-scale slicks

Lilian Lieber, Cynthia Füchtencordsjürgen, Rebecca Hilder, Paula J. Revering et autres

Data from: Selective foraging behaviour of seabirds in small-scale slicks by Lieber et al (2022) contains the HMM input file (.csv) and R analysis code (.txt) and the metadata (.pdf). All data was collected in the Narrows tidal channel, Strangford Lough, Northern …

Improved bathymetry leads to >4,000 new seamount predictions in the global ocean – but beware of phantom seamounts!

Chris Yesson, Tom B. Letessier, W. Alex M. Nimmo‐Smith, Phil Hosegood et autres

Seamounts are important marine habitats that are hotspots of species diversity. Relatively shallow peaks, increased productivity and offshore locations make seamounts vulnerable to human impact and difficult to protect. Present estimates of seamount numbers vary from anywhere between 10,000 to more than …

A bird's-eye view on turbulence: seabird foraging associations with evolving surface flow features

Lilian Lieber, Roland Langrock, W. Alex M. Nimmo‐Smith

Understanding physical mechanisms underlying seabird foraging is fundamental to predict responses to coastal change. For instance, turbulence in the water arising from natural or anthropogenic structures can affect foraging opportunities in tidal seas. Yet, identifying ecologically important localized turbulence features (e.g. upwellings …
