In a stunning encounter in the Atlantic Ocean on Sunday (July 7), a rower got up close with a large pod of whales.

Tom Waddington, a UK-based ski coach, captured footage of what he estimates were over a 1,000 long-finned pilot whales.

Waddington captured the videos while rowing solo more than 100 nautical miles off the Newfoundland coast. The images show the whales swimming around his boat, reportedly rocking it as they passed.

Reuters was able to confirm the date and location from information provided by the source’s social media spokesperson.

Waddington, who is undertaking a 2,000 nautical miles journey to raise funds for mental health charity Mind, expressed both awe and calm during this breathtaking moment at sea.
