Statement: Pulse Light and Heavy will telemeter back engineering data about mooring tension, acceleration and battery voltage. An independent system transmits GPS position. The main difference between Pulse Light and Pulse Heavy is that Pulse Heavy has an extra 450 m of wire and a water filled damper at bottom of top section. To make up for this Pulse Light has a taller bottom section. The water damper on Pulse Heavy adds inertial mass to the lower part of the top section, and because of the rubber elements higher up this mass helps to further isolate the instrument package from accelerations due to wave action on the surface float. The other benefit of having the the extra weight in the bottom of the top section is that it keeps the mooring more upright. As you can see by the figures below Pulse Light runs the risk of being completely stretched out due to current. If a wave slams surface float in when the mooring is stretched out completely the rubber elements could fail. Pulse light's advantages are; less drag (as it has a smaller subsurface profile), and less stress on the rubber element due to not having that inertial mass.
