On-board Diary: In front of the Playa de la Concha, San Sebastián

Today we’ve surveyed canyons, identified interesting places and planned future dives. While sailing towards the canyons, we sighted various groups of common and bottlenose dolphins (Delphinus delphis and Tursiops truncatus). We also found a jellyfish known as Aguamala (Pelagia noctiluca) approximately 9 miles from the coast.

During the dive, in front of Arrikola Point in San Sebastian, we found the typically Cantabrian seabed: a rocky substrate with some overhangs approximately 2 meters high covered by various types of algae, including Cystoseira, Gelidium and Falkenbergia, harbouring different types of organisms, such as sponges, nudibranchs, starfish, ascidians and sea urchins. Amongst the fish species, we identified cleaner-wrasse (Ctenolabrus rupestris), corkwing wrasse (Symphodus melops), pollacks (Pollachius pochachius) and blennies (Parablennius pilicornis).

We would’ve liked to anchor in the Concha beach in San Sebastian, but after seeing how many boats there were in the bay, we decided to return to Zumaia.
