Laser-Induced Fluorescence Emission (L.I.F.E.) as Novel Non-Invasive Tool for In-Situ Measurements of Biomarkers in Cryospheric Habitats
Published on: October 26, 2019
Summary
This study presents evidence for thicker Arctic Ocean ice during glacial periods, supported by Greenland ice core data. It also argues for a comprehensive Arctic ice cap based on deep-sea sediment analysis.
Area of Science:
- Paleoclimatology
- Oceanography
- Glaciology
Background:
- Understanding past Arctic ice extent is crucial for climate modeling.
- Previous research has yielded conflicting evidence regarding glacial Arctic ice cover.
Purpose of the Study:
- To present arguments supporting thicker Arctic Ocean ice during glacial times.
- To provide evidence for a full-fledged Arctic ice cap during past glacial periods.
Main Methods:
- Analysis of the Greenland Camp Century ice core for air temperature records using isotopic studies.
- Examination of oxygen isotope records from benthic foraminifera in a deep Pacific Ocean core.
Main Results:
- Isotopic analysis of the Camp Century ice core suggests warmer Greenland air temperatures, supporting thicker ice.
- Oxygen isotope data from Pacific Ocean sediments indicate conditions favorable for a substantial Arctic ice cap.
Conclusions:
- The findings support the hypothesis of significant Arctic ice accumulation during glacial epochs.
- Integrating ice core and deep-sea core data offers a more comprehensive view of past Arctic environments.

01:50Global Climate Change
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.
01:21Green Algae
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
02:39Phase Transitions: Melting and Freezing
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...
01:23Membrane Fluidity
Cell membranes are composed of phospholipids, proteins, and carbohydrates loosely attached to one another through chemical interactions. Molecules are generally able to move about in the plane of the membrane, giving the membrane its flexible nature called fluidity. Two other features of the membrane contribute to membrane fluidity: the chemical structure of the phospholipids and the presence of cholesterol in the membrane.Fatty acids tails of phospholipids can be either saturated or...
01:27Frost Action on Concrete
Concrete structures in cold climates, such as those along roadsides, can retain moisture. This moisture makes them susceptible to frost-related damage when temperatures fall below freezing. Adding moisture worsens the damage during temperature fluctuations, leading to repeated freezing and thawing. De-icing salts, spread over these structures to melt ice, add to the freeze-thaw cycle, and draw even more moisture into the concrete.
This freeze-thaw cycle primarily causes surface scaling, where...

01:25Microbial Mats
Microbial communities forming biofilms and mats represent complex, spatially structured ecosystems where metabolic processes are stratified according to light, oxygen, and nutrient gradients. Biofilms are initial colonization stages, only a few millimeters thick, while mature microbial mats can reach centimeter-scale thickness and display intricate vertical organization. Their structural and functional heterogeneity allows microorganisms to occupy distinct ecological niches within a few...
