- how far back do ice cores do
- 100,000 years
- why is the arctic melting faster
- it is not on land and it is surrounded by water
- how long are the sediment cores
- ten meters
- what do the rocks mean
- a rock means that it fell out of an iceberg
- why sis it important to have a PRR
- so that people can save time, money, and protect the environment
- What is remote sensing?
- studying something from a distance or without being there
- Where is there primary arctic research based
- Greenland
- does drilling ice cores destroy glaciers
- no, they refill themselves
- what does a dark brown band mean in a sediment core
- there was a dry season
- What do geo chemists study
- chemistry and geology of sediment cores
- why does the BPRC specialize in getting their ice cores from the rtropics
- 50% of the worlds surface, 70 5 of the worlds population, and 80 % of the worlds agriculture
- what is good about the polar ice cores
- they are longer back in times, but they are not very detailed
- why are fossils, coal, and petrified wood found in antarctica
- antarctica used to have a warmer climate
- Why was the name changed
- Byrd made a large donation
- Who is Dr. Lonnie Thompson
- A polar ice core spesialist
- why are they cut into 1.5 meters cores
- because they are easier to handle and transport
- what are the three milankovitch cycles
- Eccentricity(orbit), Obliquity(tilt), Precession(wobble)
- list eight ways that we know about climate change
- tree ring, ice cores, sediment cores, corals, pack rat middens, cave formations, lake/sea level rise, pollen, temperature, graphs
- When was the name changed
- 1987
- Why are Dr. Lonnie Thompson and his wife recognized for their research
- They got the biggest ice core every recorded from tropical mountain glaciers
- what are the goals of the ice core research group
- to learn about why current temperature are so unique
- how much time must pass in order for there to be a global climate change
- 30 years
- what is a ventifact
- any rock that has been smoothed or pitted by the wind which has sand and ice particles in it
- what does a paleoclimatologist study
- they study the rocks to tell us what caused the changes
- Who are Dr. Jason Box and Dr. David Brownwich
- leaders of the polar meteorology research group
- what will happen to lake levels if sea levels rise
- they will go down because everything will have to even out
- What is the primary tool used in remote sensing
- satellites
- who can borrow rocks from the polar rock repository
- anybody
- What was the original name?
- Institute of Polar Studies
- why is there a special clean room for the ice cores
- to prevent contamination
- why should we care if the glaciers are melting
- THere will be no more fresh water, and the sea level will rise, and it will affect us
- why is the slide of washington D.C. used to show sea level rise
- to get government attention
- where does the BPRC specialize in the ice cores
- the tropics
- Why might you study the melt ponds in greenland
- to see what could be trapped in the ice
- why did the climate change in antarctica
- because the ocean currents got cooler and cooled antarctica down
- When was it founded
- 1960
- how many miles of ice cores are kept at the BPRC
- 5 miles
- how many meters are the individual sections
- 1 meter
- what happened in the glacier activity
- the top and middle moved the fastest
- why are the sediment cores better that the ice cores
- the sediment cores go back further in time than the ice cores do
- what do the bugs mean
- they mean that there was a warmer climate
- which is melting faster the arctic or the ant arctic
- the arctic
- why is the ice over land melting causing sea level rise, and the ice melting over water isn't
- because the ice over land falls into the ocean
- what slowed down the bottom and the sides
- friction
- what causes sea level rise ice melting over water, or ice melting over land
- ice melting over land
- what is the standard equipment issued to all researchers going to antarctica
- goggles, a red parca, gloves, and ice pick, two orange bags, own boots, bunny boots, cramp-ons
- Why are we worried about global warming if it is just a cycle
- because it isn't supposed to happen this quickly
- what is the temperature of the cold room
- -30 degrees F
- why are cartoons useful in looking at history
- they say what is popular in the news
- what are the different kinds of transportation that they use
- horse, air, truck, hot air ballon, human, and yaks
- what does a dark band of an ice core show
- it was a dry season
- Name some of the research groups.
- Geosciences, oceanography, paleoclimatology, remote sensing, geochemistry, glaciology, polar meteorology
- what happens to water when it heats up
- it expands
- how many meters are they brought up in
- 10 meters
- what are is good about the tropical ice cores
- they are shorter back in time, but more detailed
- what causes 90-95% of the climate change
- human factors
- Who is Dr. Ken Jezek
- the PI(principal investigator) of the remote sensing group
- how many meters long is an ice core
- 400 meters
- if the small sediment cores are washed, then what is left to study
- the sand and fossils
- how far back do sediment cores go
- 200,000,000 years
