The "Dagwood Sandwich" Moon. Earlier models of Ganymede's oceans were based on the assumption that the existence of salt didn't change the nature of liquid very much with pressure. However, Dr. Vance and his colleagues found, through laboratory experiments, that salt does increase the density of liquids under the extreme conditions hidden deep within Ganymede and similar icy moons with subsurface bodies of water. Imagine adding table salt to a glass of water. Instead of increasing in volume, the liquid will actually shrink and become denser. The reason for this is that salt ions lure water molecules.
To increase your fishing success you're going to want to concentrate you're fishing efforts at two specific times of the month. These times are the four day period that coincides with either a Full Moon or a New Moon. Using these two time frames will increase you chances of success tremendously. You will find that it is not only going to improve your success, but that the chance of catching larger fish is also greatly improved during these two phases of the Moon. If knowing this simple fact is going to improve your success why would you not at least give it a try?
The team of scientists used data gathered by NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission, composed of a duo of twin spacecraft that circled Earth's Moon throughout 2012, each measuring the push and pull of the other as an indicator of lunar gravity.
