CV20024 UCC Undergrad & Postgrad Training Survey

Four stations to be completed. The theme of data collection will be connecting remote data acquisition with physical sampling of the seabed and water column.

Two Teams with alternating duties from stations 1 to 4.

Remote data aquisition will focus on MBES set up, line setting, display settings and data saving.

Ground truthing and benthos will use the Day Grab to obtain and describe physical samples of the seabed for groundtruthing acoustic interpretation and habitat characterisation.

Benthic Megafauna Data Sheet

All require the Cruise Code i.e CV20024, Date, Time, Latitude and Longtitude, Depth, Sea state, Wind Direction and Speed.

Log every station and every sampling activity at that station. This is going to be the master table in your report.

 Data for the Conductivity Temperature and Depth ( CTD ) probe.

This provides a physical description of the sediments at every station and ground truths  MBES  acoustic interpretations of the seabed.

The sheet derives from the  INFOMAR Ground Truthing and Sampling Strategy  document.

We’ll use section 4.5 as our guide to completing it.

For colour description we’ll use the  Munsell Colour matching system .

Download the  Munsel color chart app  from Playstore.

Corers penetrate deeper into sediments than grabs. Deck equipment includes a 2m    gravity corer  and a  Reineck Box Corer .

This sheet provides a field description of the structure and composition of the core sample. 

Further investigations and subsampling of stata of the core takes place onshore.

This log sheet is from the  INFOMAR Ground Truthing and Sampling Strategy  document.

This data sheet is also from the  INFOMAR Ground Truthing and Sampling Strategy .

We’ll be using section 4.7 as our guide for completing it. We’re sampling macrobenthos and  this video shows how .
