Small lander - no buoyancy

Small lander with no buoyancy
Lander with multi water sampler and 2 benthic chambers with stirrers

A small lander system for shallow water (500 m) with 2 benthic chambers sharing a multi water sampler with 24 syringes. The sampler has reverse functionality, i.e., one or more syringes is useable in reversed order for injection of preservation liquid or different tracers (e.g., labelled Carbon and Nitrogen) or similar into the benthic chamber, either on start of the sampling or later during the process.

Benthic chambers:
• Polycarbonate
• Dimensions: L x B x H: 30 cm x 30 cm x 60 cm
• Stirrer motor with pressure compensation
• Sensors attached: DO, Temperature, Salinity, Turbidity
(within chambers and outside chambers)
• Wave, tide and current meter sensors (outside the chambers)

Battery cylinders:
• Support for burn-wire system and stirrer motors

Multi water sampler:
• 24 syringes, each 100 ml
• Individual, programmable delay for each syringe
• More details can be found here

• AISI 316 stainless steel
• Adjustable leg height to control penetration into sediment
• Dimensions: L x B x H: 230 x 150 x 85 cm (adjustable height)
• Weight: 230 kg
