Summary
Ocean acidification is increasing hydrogen ion concentration in Antarctic surface waters. This study documents a projected 50% increase in acidity by 2070, impacting marine ecosystems.
Area of Science:
- Environmental Science
- Oceanography
- Climate Change Research
Background:
- Surface waters south of 60° S are experiencing significant chemical changes.
- Ocean acidification is a growing concern for marine ecosystems globally.
Purpose of the Study:
- To quantify the projected change in pH and hydrogen ion concentration in Antarctic surface waters.
- To assess the implications of these changes for the marine environment.
Main Methods:
- Analysis of pH data from surface waters south of 60° S.
- Calculation of hydrogen ion concentration changes based on pH shifts.
- Projection of future changes between 2017 and 2070.
Main Results:
- A decrease in pH by 0.2 units is projected for surface waters south of 60° S between 2017 and 2070.
- This pH change is equivalent to a 50% increase in hydrogen ion concentration since the pre-industrial period.
- The findings highlight a significant trend of ocean acidification in the Antarctic region.
Conclusions:
- Antarctic surface waters are acidifying at an accelerated rate.
- The projected increase in hydrogen ions poses a substantial threat to marine life.
- Urgent climate action is needed to mitigate further ocean acidification.

02:20Milgram's Obedience to Authority
7.4K
Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal. Eichmann’s defense for the atrocities he committed was that he was “just following orders.”

01:25Choosing Between z and t Distribution
3.7K
The z and the Student t distribution estimate the population mean using the sample mean and standard deviation. However, to decide which distribution to use for a calculation, one needs to determine the sample size, the nature of the distribution, and whether the population standard deviation is known. If the population standard deviation is known and the population is normally distributed, or if the sample size is greater than 30, the z distribution is preferred. The Student t distribution is...

01:15Distance Corrections
297
To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

01:20Power Factor Correction
545
The power transmission to a factory involves the transfer of apparent power, a combination of active and reactive power. The power factor measures how effectively electrical power is converted into useful work output. The ratio of the real power (KW) that does the work to the apparent power (KVA) supplied to the circuit.

01:14NMR Spectrometers: Resolution and Error Correction
1.1K
When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

Malpighian tubules are specialized structures found in the digestive systems of many arthropods, including most insects, that handle excretion and osmoregulation. The tubules are typically arranged in pairs and have a convoluted structure that increases their surface area.
