Underwater imaging has become a staple tool used by scientists exploring the deep ocean. Advanced camera systems are able to combine quantitative measurements from in-situ sensors with qualitative imaging to provide high fidelity multi-dimensional datasets which can be used to support a wide range of science questions. This includes benthic characterization and mapping, identification of biota and...
In support of ecosystem and fisheries studies the CSIRO has deployed a variety of towed and tethered systems to collect quantitative data to understand the distribution and makeup of mid-water biota. A series of platforms have been developed at the CSIRO which incorporate both imaging and acoustics to augment the physical samples. Although these systems provide high fidelity data, they often require...
Towed underwater imaging systems are increasingly used for a wide variety of science applications in the deep ocean. These systems augment data collected by physical sampling such as dredging and trawling, but also provide an important sampling alternative where extractive methods are unnecessary or unsuitable — such as in sensitive habitats or for repeated sampling in marine reserves. Specific applications...
In support of ecosystem and fisheries studies, the CSIRO has developed and deployed a variety of towed and tethered acoustic and optical systems to quantify fish biomass and characterize the ecosystem. The most recent of these platforms — the acoustic and optical system (AOS) — was designed to provide both acoustic and imaging data for fisheries studies. When vertically deployed the AOS can provide...
CSIRO has deployed large oceanographic moorings near the South Pole to help scientists better understand ocean dynamics in the ice forming regions around Antarctica. A standard instrument on these moorings is an Acoustic Doppler Current Profiler (ADCP), which provides information on the direction and magnitude of ocean currents in the water column. These instruments use an integrated magnetic compass...
Scientists looking to ground truth data collected by in situ sensors require physical water samples collected at the sensor depth. These samples which are processed in the lab are crucial in increasing the confidence of in situ sensors; especially when such sensors are of a new type. Traditionally, water samples at depth are collected manually through the use of niskin style bottles, or with the simple...
We describe an unusual pseudotumor of the upper thorax, axillary, and shoulder girdle region with presentation 4 years after a surfing sports injury. We offer the coined term “Surfinoma” to describe a pseudotumor arising from a penetrating piece of fiberglass surf board, which induced a foreign body reaction.
