Document Summary
Atmospheric pressure: point b: water"s temp at maximum density, point c & d: ice density is smaller than water. Latent heat: vaporization: melting, maritime climate: small seasonal change moderated by ocean due to large specific heat, continental climate: large seasonal change. 1000g: forchammer"s principle of constant proportions of various samples of seawater may vary, the ratio of major salts is constant states that the salinity. Principles of constant proportions: pacific: 30 ppt 55, atlantic 35 ppt 55, new method to measure salinity: salinity is proportional to electrical conductivity of ocean water. Depths: the density of seawater increases with increasing salinity, decreases with increasing temperature. Refraction: bending the waves, which occurs when waves travel from one. Sunlight does not travel well in the ocean (scattering and absorption weaken light), this is why we use sounds. Waves always bend towards slower propagation speed media. Most of the ocean lies in complete darkness. The speed of sound depends on temperature, depth, and salinity.
