I don't think this is a question that can be easily answered without a great deal of research. Even then it would not reveal the true total. You are looking at a time scale of at least a thousand years: the Vikings, Renaissance exploration, the Atlantic Slave Trade, European migration, two world wars, storms, hurricanes and icebergs. Accurate records exist only for more recent times so we know how many people were lost for example, on the Titanic.

1514 people died when the titanic sank.
2,300
All 230 people on board TWA Flight 800 died when the aircraft crashed into the Atlantic Ocean on July 17, 1996.
1500 people died. 715 lived. Most of the people who died, died from exposure to the cold icy water of the North Atlantic. Hypothermia was the cause of most people's death in the Titanic disaster.
First ocean crossing by boat? Surely the skin boats used by the Irish and some of the Pacific people were capable of ocean crossings. I have sailed on the Atlantic myself for many years and met at least six people who crossed the Atlantic alone in small sail or man powered boats, so I know it can be done. The technology was there 2000 or more years ago, so why not sail the ocean rather than wait for some "land bridge"?
