ἐκβολὴν ἐποιοῦντο

(Some words not found in SR-GNT: σφοδρῶς Δέ χειμαζομένων ἡμῶν τῇ ἑξῆς ἐκβολήν ἐποιοῦντο)

The word jettison is a nautical term that describes sailors throwing the cargo of a ship (the goods that the ship is transporting) into the sea to lighten the weight of the ship in an effort to prevent it from sinking. If your language does not have a comparable nautical term, you could state the meaning plainly in your translation. Alternate translation: [they were throwing the cargo of the ship into the sea to make the ship lighter to try to keep it from sinking]
