SST
Sea Surface Temperature
EBB
outgoing tide / water level decreasing
Flood
incoming tide/ water level increasing
Three Ocean Layers
MIXED- upper layer, warmer warmer, 1500 ft.
Thermocline- central layer, rapid decrease in water temperature
Deep Layer- cold temperature, less than 4 degrees celcius
Air Mass
Large Volume of air defined by its temperature and water vapor content.
Occluded Front
formed during the process of cyclogenisis. cold front overtakes a warm front.
5 parameters for a cyclone to occur
1.pre-existing tropical disturbance
2. sea surface temperature of >79
3. favorable coriolis
4. divergence aloft
5. minimal.low vertical windshear
tropical depression
tropical cyclone with wind speed of 33kt or less
tropical storm
tropical cyclone with wind speed of 34-63 kts
hurrican/typhoon
tropical cyclone with wind speed of 64kts or more
ocean eddies
rotating masses of water that have broken off from a strong front/current.
i.e. gulf stream resulting in salinity and density variations.
sea wave
waves that have been created by local winds
swell waves
seas that have moved out and away from the area tin which they were formed
temperature
sound speed decreased at lower temps. speed increases 6ft per sec per degree
pressure
pressure increases with depth and sound speed increases with higher pressure. sound speed increases 2ft per sec per 100ft of depth
salinity
slight effewct in open ocean. major fact in shallow water.
standard refraction
refraction that would take place in an idealized atmosphere where the refractive index is reduced uniformly with height.
super-refraction
radar beams bends toward the ground instead of continuing upwards, usually caused by night cooling or marine inversion
sub-refraction
causes radars to overshoot target that are normally detected. usually occur in desert regions and mtn ranges
trapping/ducting
extension on super-refraction. can extend radar ranges.
small craft
winds 33kts or less for harbor and inalnd waters
gale
34-47 kts for harbor and inland water
high seas
waves of 12ft or higher
typhoon/hurricane
warning for land, harbor, inland waters and ocean areas for winds 65 knts or higher.
OTSR
Optimum Track Ship Routing
-advisory service whose primary mission is safety.
5 environmental conditions
1.water depth - pressure
2. currents- drifts
3. tides- litteral movement
4. transparency - visibility
5. temperature - warm waters reduce battery life.
Oceans
pacific, arctic, southern, atlantic, indian ocean
relief features:
sub volcanoes, seamoutns,. sub mt ridges
