1. A system for collecting and analysing samples from an open water environment, the system comprising:
a collection module configured to float within and receive water samples from a surrounding open water environment, the collection module comprising one or more filters for collecting objects of a target size range from the water samples;
a filtration module comprising a filter configured to separate the collected objects according to a predetermined parameter and comprising outputs for the filtered and unfiltered objects;
an analyzation module comprising an imaging device and a processing device, the analyzation module configured to image the unfiltered objects from the filtration module to determine one or more characteristics of parameters of the unfiltered objects,
whereby the collection module, the filtration module and the analyzation module are operatively connected together to collect and analyze samples from the open water environment.
