Measuring rainfall from above and below the sea surface

Satellites play a major role in the determination of the rainfall at sea. Researchers at Southampton Oceanography Centre (SOC) have been involved in two projects addressing this task. First they have been instrumental in developing techniques to retrieve

The effects of playbacks of anthropogenic noise on the anti‐predator behaviour of Pacific sand lance, Ammodytes personatus

Journal of Fish Biology, EarlyView.
Abstract Noise from human activities has increased and been shown to negatively impact marine animals. Marine mammals and fish are vulnerable to anthropogenic noise because they rely on sound to communicate, find food, avoid predators and sense their environment. Forage fish are small schooling pelagic fish, important to many predators and instrumental

Social context shapes acoustic signalling in the territorial damselfish Stegastes fuscus

Journal of Fish Biology, EarlyView.
Abstract Acoustic communication plays an important role in social interactions in reef fishes, but how signals vary with behavioural context remains poorly understood for many species. We characterised the acoustic repertoire of the Brazilian damselfish Stegastes fuscus using synchronised underwater audio–video recordings and tested how sound features ...

Seasonal presence, movements and behaviour of Atlantic cod (Gadus morhua) in Isfjorden, Svalbard

Journal of Fish Biology, EarlyView.
Abstract Atlantification is increasing the inflow of warm, salty Atlantic water into the Arctic region. The fjords on the western coast of Svalbard are experiencing Atlantification, enabling boreal species, such as Atlantic cod (Gadus morhua), to expand their distribution northwards.

Effect of visual and electrosensory deterrents on captive elasmobranchs

Journal of Fish Biology, EarlyView.
Abstract Commercial gillnet fisheries interact with a wide range of elasmobranch species, many of which are incidentally captured as bycatch. Deterrent technologies have emerged as a potential approach for reducing interactions with threatened elasmobranchs.
