FAQs

How to calculate sea surface temperature? ›

A: Satellite instruments measure sea surface temperature—often abbreviated as SST—by checking how much energy comes off the ocean at different wavelengths. Computer programs merge sea surface temperatures from ships and buoys with the satellite data, and incorporate information from maps of sea ice.

The temperature of ocean water varies by location – both in terms of latitude and depth, due to variations in solar radiation and the physical properties of water.

AVHRR (MetOp-1/2) Level 2/3

NOAA CoastWatch / OceanWatch / PolarWatch produces Level 2/3 sea surface temperature datasets using AVHRR sensors aboard the Metop 1/2 satellites.

To measure SST, scientists deploy temperature sensors on satellites, buoys, ships, ocean reference stations, and through marine telemetry. The NOAA-led U.S. Integrated Ocean Observing System (IOOS®) and NOAA's Center for Satellite Applications and Research (STAR) merge their data to provide SSTs worldwide.

NOAA's satellites utilize microwave and infrared radiometers to measure sea surface temperatures, giving researchers valuable clues about the ocean. The ocean is home to critical coral reef ecosystems that provide a home to millions of plant, fish and marine animals.

The surface temperature of the world's oceans varies mainly with latitude, with the warmest waters generally near the equator and the coldest waters in the Arctic and Antarctic regions.

Temperature of ocean water is not uniform and several factors like insolation, prevailing winds, ocean currents, affect its distribution. There is a gradual decrease of temperature from equator towards poles and the rate of decrease of temperature is generally of the order 0.5° per latitude.

However, in general, the Atlantic Ocean's waters are warmer near the equator and colder near the poles compared to the Pacific. Please note that many variables can influence ocean temperatures. Why is science important?

Temperature profiles vary at different latitudes, as the surface water is warmer near the equator and colder at the poles. In low latitude tropical regions the sea surface is much warmer, leading to a highly pronounced thermocline (Figure 6.2. 4).

Sea surface temperature is a key climate and weather measurement obtained by satellite microwave radiometers, infrared (IR) radiometers, in situ moored and drifting buoys, and ships of opportunity.

At what depth is sea surface temperature measured? ›

Ocean Temperature is a measure of the energy in the ocean due to the motion of molecules. Depending on the sensor, spaceborne measurements give us an unprecedented global measurement of ocean temperatures from approximately 10 µm below the surface to 1 mm depths using radiometers.

The TOPEX/Poseidon spacecraft uses a high precision radar altimeter to take measurements of sea surface height over 90% of the world's ice- free oceans. The satellite orbits at an altitude of 1336 km above the Earth and at an inclination of 66 degrees.

The temperature of seawater is measured using instruments called thermistors. The temperature of seawater can be measured to great accuracy with carefully calibrated modern thermistors - down to variations of 0.0001^° C. We measure temperature from a number of different platforms in the OSMOSIS project.

Answer:​ Maps can display data patterns over large areas, but often with less detail or resolution than graphs. Graphs represent a “slice” of data along a line, but can show smaller variations.

Surface temperature is measured with a hand-held Infrared Thermometer (IRT) that, when necessary, is wrapped in a thermal glove or has been placed outdoors for at least 30 minutes prior to data collection.

Sea surface temperature is defined as the average temperature of the top few millimeters of the ocean. Sea surface temperature monitoring tells us how the ocean and atmosphere interact, as well as providing fundamental data on the global climate system.

The heart of the sea must be found. It cannot be crafted or obtained by trading, making it a non-renewable resource. A heart of the sea is obtained from a buried treasure. The location is marked with a noticeable red X on a buried treasure map, which is found in ocean ruins and shipwrecks.
