On the first dive we will explore the Tica Vent area and Teddy Bear/East Wall area to locate potential places for our three experiments, test the ISMS, test water sampling with MBSG, and collect rocks, a tubeworm clump and a mussels clump, water with one Niskin bottle, deploy colonization devices (sponges).

After having selected the location for our first experiment, this dive is dedicated to start experiment 1 with measuring temperature at the selected tubeworm clump, followed by ISMS measurement. A water sample will be taken in the tubeworm clump. Afterwards the tubeworm clump will be sampled. Some rocks will be taken. A mussel clump + rock, and 3 Niskin bottles will be sampled. If time allows, we will proceed in the ASCT further north.

We will continue with our experiment and will place the meshbox over the cleared area ,seal it to the bottom, pace the staining box over the mesh box and dye for severalhours. Afterwards the dye will be removed back into the blue bag. The mesh box will be at the bottom for several days. If time permits we will explore further north up to Biovent.

We will first search for a place for the second experiment in the area of the first experiment. After selecting on place, we start with experiment 2 with measuring temperature at the selected tubeworm clump, followed by ISMS measurement. A water sample will be taken in the tubeworm clump. We will sample tubeworms, mussels, rocks, and 3 Niskin bottles.

We will first deploy some experiments (Austrian and Slovenian School, Max Schneider deployment 1) at Tica and take highlight videos. We then go to waypoint 11 and 13 for images on meshbox 1 and 2. We select a site for our experiment 3 in the vicinity with measuring temperature and placement of the frame In a closeby control area we will also measure temperature and do a ISMS measurement, and will take a water sample in the tubeworm clump. We will sample the tubeworm clump and slurp over the area. We will go back to Tica and sample tubeworms, mussels, rocks and 3 Niskin bottles. Then we will visit the school deployments and Max Schneider’s first deployment, take highlight videos of all and recover Max Schneider’s deployment.

We will first go to Tica to check on School Experiment and Max1. We go North to Fava Flow Suburbs to check on deployed three meshboxes. We do our control basalt experiment 2, measure temperature, collect water above basalt and collect basalt. We go to a tubeworm clump and measure temperature at base, and fill the small bag with 1 L of water. Then we go North, check all smokers there (M Vent, Flea Vent, Q Vent, Biovent) and select rocks (basalt and chimney) to sample. We also search for tubeworms and Mussels at Peseverance and Biovent and select place to collect them. If time permits we go further North in the ASCT.
