Below sea level atmospheric pressure increases with depth.
Air pressure at sea level is about 14.7 psia. Air pressure below sea level would be slightly higher.
The highest altitudes have the lowest air pressure. Air pressure increases as altitude decreases. Above sea level is lower pressure; below sea level is higher pressure.
Assuming you are talking about air pressure, atmospheric pressure is created by the weight of the air resting against the earth. the higher up you go, the less air stacked on top of itself, and the pressure is less, until there is no more air at all (space). The pressure of air at sea level is relatively the same around the world because of all the water flows to the same level. this obviously changes with storms and hurricanes - as those move some of the air out of the way. So if you were to go below sea level, there would be more air on top of you, and the pressure would be higher. In death valley (well below sea level) the atmospheric pressure is much higher than at sea level. To answer the question, No, pressure is not negative below sea level. It is greater than at sea level.
I would expect it to be lower.
The pressure at different altitudes depends on the weight of the air column above that point. At 14000 ft above sea level, there is less air above causing lower pressure (0.69 ATM). Conversely, at 14000 ft below sea level, there is more air above causing higher pressure (470 ATM).
Sea level pressure, sometimes as mean sea level pressure.
The air pressure is greatest at sea level.
The highest altitudes have the lowest air pressure. Air pressure increases as altitude decreases. Above sea level is lower pressure; below sea level is higher pressure.
Air pressure in a valley below sea level would be higher than at sea level. This is because the weight of the air column above is greater in the valley due to the higher density of air molecules compressed into a smaller volume.

on the bottom of the mountainbeacause you are more below air level
Atmospheric pressure is the weight of the air above the surface of the earth. As elevation increases, there is less air above the location and the pressure is lower. At sea level the column of air above the area is greater.?æ
The pressure at different altitudes depends on the weight of the air column above that point. At 14000 ft above sea level, there is less air above causing lower pressure (0.69 ATM). Conversely, at 14000 ft below sea level, there is more air above causing higher pressure (470 ATM).
It's not so much that the air pressure below a wing is greater as it is the pressure above it is less. The way a wing works, is the airfoil (shape of the wing) accelerates the air above the wing. Since the air is moving faster, it lowers the air pressure, resulting in a lower pressure above, and a higher(standard) pressure below, creating lift.
