Travelling the deep water of the south-east Indian Ocean with several daily sonobuoy deployments, the most prevalent acoustic detections by the Jenners so far, have been pygmy blue whale calls.
Deep-sea fishes reside at depths greater than 200 m beyond the effective influence of sunlight for most of the time.
Living in the clear waters of the open ocean is a dangerous business when you are a small swimming organism because there is nowhere to hide from predators.
On our voyage with the RV Investigator, along the 110°E meridian in the south-east Indian Ocean, in addition to filtering very tiny organisms from water samples, we are using a wide variety of nets to capture plankton.
Studying how ocean systems differ in terms of how productivity moves through micro- versus mesozooplankton is a basic approach to characterising their different relative functions in nutrient recycling, trophic transfers and carbon export.
Phytoplankton–the microscopic plants inhabiting the surface lit layers of the ocean are among the most diverse group of micro-organisms inhabiting the planet.
What are these microbes and what are they doing? Onboard RV Investigator a team of microbiologists is addressing these questions using modern molecular methods.
The CSIRO scientists involved in the original International Indian Ocean Expedition during the 1960s described it as a desert.

The RV Investigator departed Fremantle this week after loading equipment and supplies for our month-long voyage as part of the second International Indian Ocean Expedition.
On 14th May 2019 at 3PM WST, the Research Vessel Investigator departs Fremantle on an oceanographic voyage to the 110°E meridian in the south-east Indian Ocean following in the wake of the HMAS Diamantina.
