New BATHY reporting code form

A new form of the BATHY code has been approved and will come into effect on 3 May, 2000. Everyone encoding observations into BATHY and decoding observations from BATHY should make the necessary software changes in time to send and receive this code form.

The new form is a slight modification of the present form. The only change is in the code form identifier and in the way latitudes and longitude are reported. Below is shown the complete code form with the changes highlighted in bold. M
