When you go to charge your battery in the battery charger and experience any error when doing so or if the battery doesn't charge at all then the battery is most likely short circuited.

Otherwise most likely the saltwater has corroded the various components of the camera and you would need to replace every circuit inside your camera. Therefore, your best option would be to buy a new camera. Feel free to refer to our troubleshooting guide for further help with your Nikon camera. Nikon D3000 Troubleshooting
