FFerries, cargo ships and tankers cut through choppy waters in San Francisco Bay on Tuesday when a whale surfaced nearby, its spout barely visible against the white caps. Until now, whales could easily go unnoticed by sailors, but an AI-powered detection network launched this week aims to track them day and night.
