Zebra-Tech Hydro-Wiper The Hydro-Wiper is an innovative mechanical wiper system designed to keep the windows of optical sensors clean. It is  designed to fit easily to a wide variety of instruments, and is also used very successfully for underwater cameras. Using a regular gentle brushing action, the Hydro-Wiper keeps the optical window of the instrument clear of bio-fouling and unwanted mud deposits. This reduces the need for expensive site visits to clean the instrument  by hand, and helps to maintain…

McLane ITP – Ice Tethered Profiler The McLane ITP is a moored profiler which has been designed to be deployed through a small hole under the ice. It collects measurements of conductivity, temperature, and depth, and other sensors. Data is recorded on board, and can be transmitted automatically in near real time using an inductive modem connected to a surface controller. Deployment parameters including profiling depth, time intervals and pressure stops are pre-programmed by the user, and profiling patterns can…

McLane Glass flotation is based on 12″ spheres McLane Glass flotation is ideal for deep ocean moorings and instruments. All McLane Glass flotation modules are based on 12″ borosilicate glass spheres protected by polyethylene hardhats, and depth-rated to 7,000m. The multi-sphere hardhats have a central tension rod for installation in a mooring line. This eliminates mooring cable twist for better performance. G2200 single sphere model (10kg buoyancy), G6600 triple sphere model (30kg buoyancy) G8800 quad sphere model (40kg buoyancy). Download…

McLane MMP Moored Profiler climbs up and down a wire The McLane Moored Profiler (MMP) travels up and down a fixed mooring wire, carrying a selection of oceanographic sensors. Standard instruments include a CTD and an acoustic current meter. Additional sensors often include a variety of bio-optical, chemical, and suspended particle sensors. The profiling depth and interval and optional pressure stops are all programmable by the user, and acquired data is recorded on board. Optional inductive modems can be used…

McLane Large Volume Samplers can pump 36,000 litres of sea water The McLane Large Volume Water Transfer System (WTS-LV) is used to collect a single sample onto a 142mm membrane filter by drawing ambient water through the filter holder without passing through the pump first. It is most commonly deployed suspended from the hydrowire of a research vessel. Depending on the filter installed it may be used to collect suspended particles, particulate trace metals, phytoplankton or micro-plastics. The WTS-LV is…

The McLane PPS collects 24 samples of suspended matter The McLane PPS Phytoplankton Sampler is a self-contained unit that collects up to 24 particle samples from the water onto 47mm filters membrane filters. The samples are collected in a user-defined time series and can be analyzed for trace metals, phytoplankton and suspended particles. The patented multi-port valve isolates individual samples and distributes water directly to the sample filter so that it is not contaminated by passing through a pump. An…
