Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Green Algae

Green 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...

The Carbon Cycle

The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Area of Science:

Geology
Sedimentology
Planetary Science

Background:

Sediment recycling is key to Earth's geological record.
Mars exhibits minor tectonism but significant sedimentary rock erosion.
Orbiter data reveal buried Martian sedimentary rocks exposed at the surface.

Purpose of the Study:

Investigate extraformational sediment recycling on Mars.
Analyze recycled sediments in Gale crater using rover data.
Predict recycled sediment presence at future Mars landing sites.

Main Methods:

Analysis of sedimentary lithoclasts in Gale crater by the Curiosity rover.
Examination of four distinct locations within Gale crater.
Interpretation of Mars orbiter images of sediment fans.

Main Results:

Discovery of sedimentary lithoclasts (rock fragments) within sedimentary rocks at four Gale crater sites.
Identification of immature, physically weathered recycled sediments.
Observation of lithified sediment fans composed of recycled material.

Conclusions:

Mars has experienced significant extraformational sediment recycling, similar to Earth.
Physical weathering dominated the observed sediment recycling cycles.
Future rover missions may encounter recycled sediments in deltaic deposits.
