Argus Bank - Bermuda Diving

Site Overview

Argus Bank is an enormous submerged geological formation rising from depths exceeding one thousand metres to within sixty metres of the surface creating an isolated deep-sea seamount ecosystem in the open Atlantic. This rarely visited formation hosts uncharted reef communities on its shallowest pinnacles and attracts extraordinary concentrations of pelagic life including oceanic whitetip sharks massive schools of jacks and tuna. The seamount creates upwelling currents that deliver nutrients from the deep ocean supporting biodiversity found nowhere else in Bermuda waters. Accessing Argus Bank requires expedition-style logistics with dedicated charter vessels technical diving equipment and trimix certifications for the extreme depth profiles. The pristine seamount communities remain virtually untouched by human activity providing genuine exploration opportunities for technical divers and marine researchers. Argus Bank represents the frontier of Atlantic diving offering experiences that fewer than a handful of divers worldwide have encountered. The deep diving environment at Argus Bank supports a productive marine ecosystem where nutrient-rich Atlantic waters sustain diverse coral communities and tropical fish populations throughout the diving season. Underwater photographers will find excellent compositions combining the natural beauty of the reef structure with abundant marine life in clear Atlantic waters. The site contributes important biodiversity value to Bermuda diving portfolio offering experiences that complement the more commonly dived locations while providing equally rewarding underwater encounters for visiting divers. Seasonal visitors including green sea turtles spotted eagle rays and migratory pelagic species add excitement to every dive with the possibility of unexpected encounters keeping divers engaged throughout their exploration of this productive deep diving site.
