A unique way to sample microplankton in the deep sea.
Deep ocean plankton
This new plankton net consists of an external PVC and stainless steel frame, with a 20µm plankton net inside it. Allows the collection of microplankton samples at any depth, even deeper than 4000m, where this type of sampling has never before been carried out.
This results in novel data for researchers studying the marine environment, including the composition of deep ocean plankton communities (below 1000 m depth), which can be used in a multitude of studies (trophic relationships, molecular biology, population dynamics, etc.).
Opening and closing
The automatic opening and closing system that is operated remotely via an oceanography rosette mechanism, allowing you to take samples at a specific interval in the water column. For example, you could sample the plankton between depths of 3000m and 2000m, or 3000m and 1000m.
The Bottle net has been designed so that it can be placed into a classic oceanographic rosette, and it can use the same closure mechanisms as the other bottles. In addition, it has an adjustable clamp system that enables it to be placed in this type of oceanographic rosette.

Net for Bottle-net
The 20µm plankton nets are conical-conical shaped and designed for optimal filtration efficiency at speeds of <1m/s. The cod end of the net is designed to fit our CP3-50B plankton net bucket, specially designed for the Bottle net.

Once the sample has been collected, the design of the bottle allow you to easily access the plankton collector. In addition, our CP-50B bucket can be removed and replaced rapidly, thanks to the design of its thread.

Please find a link to one of the articles that used the Bottle net to take samples. In this case, it was used during the Malaspina 2010 Circumnavigation Expedition, where researchers were able to confirm that fast-sinking mechanisms inject fresh organic carbon into the deep sea and that this is a prevalent process operating across the global oligotrophic ocean.

The Bottle net was designed and developed in line with a patent owned by the University of Cadiz.
