ASL Environmental Sciences has an annual competition for an early career scientist to win the lease of one of our instruments for several months. This year’s competition is for the use of ASL’s newest product, the AZFP-nano. We designed the AZFP-nano as compact, calibrated 200 kHz single beam echosounder that can tag along on almost any underwater profiler, vehicle, or even a kayak! I’ve been testing it as add-on to various CTD profilers to get echograms and backscatter indices throughout the water column.
Very nice to see the nano in action! Well done, looking forward to see more applications.
I couldn’t see weight or size specifications in the borchure, just interested how easy it would be to mount on an underwater drone.
We’re working with two versions right now, a shallow water version with an acetal pressure case that’s good to 300 m or so and a deep version with a titanium case that’s good to 2000 m or so.
The latter we designed for profiling floats, similar to Argo.
The diameter of the pressure case is ~10 cm, length is ~35 cm. weight in air = 3.2 kg + 1.3 kg (9 D-cell batteries).
The diameter of the MSI transducer is 8.9 cm, height is 7 cm. approx weight in air = 0.8 kg
There’s an even smaller version called the pico that is powered externally.
Here’s a pic of the whole kit, deep version(lying on sheep skin, because I took it to Chile ).
