- Hydrography- This refers to the temperature and salinity
properties of seawater. The physical characteristics of waters with
different temperature and salinity profiles may indicate different water masses and their subsequent movements. Sea surface temperature represents one of the earliest oceanographic records.
Today sea surface temperature represents one of the widely measured physical
oceanography parameters and there are several sea surface temperature
products at different spatial and temporal resolutions.
- Currents
- Ocean waters are constantly moving. Current flows in complex
pattern affected by wind, salinity, heat content of water, bottom topography
and the earth's rotation. Currents movement influence climate and
living conditions of both plants and animals.
- Sea Level - Mean sea level is the average height of sea with
reference to a suitable reference surface. Sea level has changed over
geologic time and is more prone to rise than fall today. Small changes
can have noticeable impacts on plants and animals.
The Global Sea Level Observing System (GLOSS) is a programme coordinated by
the Intergovernmental Oceanographic Commission (IOC) for the establishment
of global and regional sea level networks. The GLOSS Station Handbook provides information on each of the tide gauges in
GLOSS core network that makes their sea level data (hourly values)
available.
