Thermosensation

Thermosensation

Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Precipitation Gravimetry

Precipitation Gravimetry

Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

Temperature Measurement Sites

Temperature Measurement Sites

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Thermometers and Temperature Scales

Thermometers and Temperature Scales

Any physical property that depends consistently and reproducibly on temperature can be used as the basis of a thermometer. For example, volume increases with temperature for most substances. This property is the basis for the common alcohol thermometer and the original mercury thermometers. Other properties used to measure temperature include electrical resistance, color, and the emission of infrared radiation.
As many physical properties depend on temperature, the variety of thermometers is...

Constant Pressure Calorimetry

Constant Pressure Calorimetry

Calorimetry is a technique used to measure the amount of heat involved in a chemical or physical process or to measure the heat transferred to or from a substance. The heat is exchanged with a calibrated and insulated device called the calorimeter. Calorimetry experiments are based on the assumption that there is no heat exchange between the insulated calorimeter and the external environment. The well-insulated calorimeters prevent the transfer of heat between the calorimeter and its external...

Gas Thermometers and the Kelvin Scale

Gas Thermometers and the Kelvin Scale

The definition of temperature in terms of molecular motion suggests that there should be a lowest possible temperature, where the average kinetic energy of molecules is zero (or the minimum allowed by quantum mechanics). Experiments confirm the existence of such a temperature, called absolute zero. An absolute temperature scale is one whose zero point is absolute zero. Such scales are convenient in science because several physical quantities, such as the volume of an ideal gas, are directly...

Area of Science:

Oceanography
Seismology
Climate Science

Background:

Greenhouse gases trap energy, with oceans absorbing over 90% of this heat.
Monitoring deep-ocean warming is difficult due to sparse data points.
Existing methods struggle to capture basin-scale temperature changes.

Purpose of the Study:

To introduce a novel method for inferring basin-scale deep-ocean temperature changes.
To complement traditional point-based ocean temperature measurements.
To provide a more comprehensive understanding of ocean warming dynamics.

Main Methods:

Utilizing sound waves generated by repeating earthquakes.
Applying seismic ocean thermometry to analyze wave travel times.
Constraining temperature anomalies in the equatorial East Indian Ocean over a 3000 km section.

Main Results:

Successfully constrained temperature anomalies with a standard error of 0.0060 Kelvin.
Detected temperature fluctuations on various timescales (12 months, 6 months, ~10 days).
Inferred a decadal warming trend significantly higher than previous estimates.

Conclusions:

Seismic ocean thermometry offers a viable method for monitoring deep-ocean warming.
The study highlights substantial and accelerating warming in the East Indian Ocean.
Findings underscore the urgency of addressing greenhouse gas emissions and their impact on oceans.
