A gallery of some pictures from our research:

Autosub-2
about to be recovered to RRS James Clark Ross in the Antarctic.
The echosounder transducers are visible near the nose.

Towed
body for deployment of echosounder transducers from a large research
vessel: RRS Discovery in this case.

|
Housed
scientific echosounder and deployment frame. This is used for making
acoustic observations in deep (500 m) water.

Benguela from RV Dr Fridtjof Nansen.

Multinet sampler for zooplankton collection at five different depths. Operated in the Namibian Benguela to collect information on the abundance of non-gelatinous zooplankton. This data allows us to correct our jellyfish acoustic data for acoustic backscatter from non-gelatinous zooplankton. | |
