Summary
Paleotemperature proxy data are crucial for understanding Earth's climate history. The PhanSST database offers over 150,000 sea surface temperature data points spanning the Phanerozoic Eon for research.
Area of Science:
- Paleoclimatology
- Geochemistry
- Oceanography
Background:
- Paleotemperature proxy data are essential for reconstructing past climates.
- Understanding Earth's climate evolution requires comprehensive datasets.
- The Phanerozoic Eon represents a vast timescale of significant climate variability.
Purpose of the Study:
- To introduce PhanSST, a novel database of paleotemperature proxy data.
- To provide a comprehensive resource for estimating past sea surface temperatures.
- To facilitate paleoclimate research by consolidating diverse proxy data.
Main Methods:
- Compilation of over 150,000 data points from five proxy systems.
- Inclusion of geochemical data with near-global spatial distribution.
- Association of each proxy value with detailed metadata (location, age, taxonomy).
Main Results:
- The PhanSST database spans most of the Phanerozoic Eon.
- Data includes expert-assigned diagenetic assessments and ecological flags.
- Quality control checks and updated foraminiferal taxonomy ensure data reliability.
Conclusions:
- PhanSST is a valuable, transparent, and reproducible resource for the paleoclimate community.
- The database supports diverse research applications, including evolutionary and geochemical studies.
- PhanSST promotes informed reuse of paleotemperature data for climate research.

01:50Global Climate Change
24.7K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

01:14Temperature Measurement Sites
2.0K
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...

01:03Precipitation Gravimetry
6.8K
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...

01:27Diversity of Protists III
98
Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

02:56The Fossil Record
25.3K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
