Submersible optical sensors exposed to chemically dispersed crude oil: wave tank simulations for improved oil spill monitoring.

In situ fluorometers were deployed during the Deepwater Horizon (DWH) Gulf of Mexico oil spill to track the subsea oil plume. Uncertainties regarding instrument specifications and capabilities necessitated performance testing of sensors exposed to simulated, dispersed oil plumes.

Subsoil drain sumps are a key container for Aedes aegypti in Cairns, Australia.

The contribution of subterranean drain sumps to pupal and adult populations of Aedes aegypti is reported for the 1st time in Cairns, Australia. Pupal surveys were used to quantify the relative contribution of drain sumps to the total population of Ae. aegypti by concurrent survey of sump and water-bearing containers in yards of inner-city premises.
