Gemma
Why dive here
With 33+ marine species recorded in the area - including sperm whales - Gemma offers some of Mar del Plata's richest wreck diving. Water ranges 10-21°C, warmest January, February, March.
The *Gemma* wreck, sitting in just 4m of water off Mar del Plata, is an interesting option for newer divers or those looking for a shallow second dive. It’s a broken, exposed hull, very much a skeleton rather than a pristine vessel. What you’ll find here are small crabs, anemones, and a scattering of fish that have made homes in the twisted metal. It’s a site to explore slowly, appreciating the way the ocean reclaims human structures.
