1 Overview of Polar Oceans by Maria (Masha) Tsukernik
2 Masha Tsukernik Research Fellow, Monash University, Melbourne Australia I am a bipolar scien>st, studying changes in polar atmosphere, oceans and cryosphere (snow and ice). I am fascinated by sea ice the most!
3 Overview Why are the polar regions important for global climate? What changes have been observed in polar oceans? So what?
4 Why are the polar regions important?
5 Why are the polar regions important? The Earth is heated unevenly Polar regions are the A/C of the planet
6 Why are the polar regions important? The Earth is heated unevenly Atmosphere and ocean are correc>ng imbalance Atmospheric circula>on in theory and prac>ce
7 Why are the polar regions important? Thermohaline circula>on in the ocean
8 Why are the polar regions important? 1. Polar regions play a crucial role in the global atmosphere and ocean circula>ons
9 Why are the polar regions important? Sea ice, ice sheets, seasonal snow cover all WHITE
10 Why are the polar regions important? Ice albedo posi>ve feedback Snow/ice surface reflects sunlight Dark ocean surface absorbs sunlight Once melt starts, it is amplified by the feedback loop
11 Why are the polar regions important? 1. Polar regions play a crucial role in the global atmosphere and ocean circula>ons 2. Polar feedbacks (e.g. ice- albedo posi>ve feedback) intensify changes that occur at the poles
12 Arc$c Ocean Best known for its ice cover Average depth of Arc$c Ocean: 1038 meters (3407.) Deepest point in the Eurasian Basin: 5450 meters (17,881.). En>re basin: 1.5 3mes the size of the con>guous US
13 What changes have been observed? hxp://nsidc.org/arc>cseaicenews/
14 Arc>c summer sea ice is decreasing with accelerated rate
15 Arc>c sea ice This anima>on illustrates how sea ice (in grey) grows in winter The seasonal cycle and local weather s>ll play a big role in day- to- day sea ice changes!
16 What changes have been observed? Greenland melt CIRES/NSIDC
17 Greenland glaciers Jakobshavn Isbræ drains 6.5% of the Greenland ice sheet and produces around 10% of all Greenland icebergs
18 What changes have been observed? Accelerated melt in Greenland Moulins and water lubrica>on
19 Antarc$ca: frozen solid
20 What changes have been observed? This anima>on shows a collapse of Larsen B ice shelf in February 2002 it was the first >me in history ice shelf collapse was monitored NSIDC
21 Ice shelf collapse hxp://nsidc.org/news/press/ _wilkins.html
22 Summary of observed changes Arc>c sea ice cover in summer is decreasing Greenland glaciers are mel>ng at accelerated rate Ice shelves around Antarc>ca are collapsing
23 So what?
24 Arc>c sea ice faster then forecast More energy from the Sun will be absorbed Erosion, storm surge, changes in salinity- driven circula>on Decreasing habitat for Arc>c animals No direct increase in sea level (sea ice is floa>ng) Stroeve/NSIDC
25 Accelerated ice loss in Greenland and Antarc>ca: Polar regions are fascina>ng New data and new discovery awaits What happens at the poles affects us all
26 Poten>al sea level rise East Antarc>ca: 64.8m West Antarc>ca: 8.06m Antarc>c Peninsula: 0.46m Greenland: 6.55m Other glaciers: 0.45m TOTAL: m USGS
27 Thank you!
28 Trivia Most of the world s salt water is in the oceans. On which con>nent is most of the world s fresh water? _ Africa _ Antarc>ca _ Asia _ Australia _ Europe _ North America _ South America
29 Trivia What will happen to sea level rise if the summer Arc>c sea ice disappears?
30 Trivia At which loca>on would you be at the highest eleva>on above sea level? _ Base of Vail Ski Resort _ Highest point in Australia _ Highest point east of the Mississippi _ South Pole
31 Arc>c vs. Antarc>c sea ice Summary of differences between Arc$c and Antarc$c sea ice characteris$cs Arc>c Antarc>c Average Maximum Areal Extent 15,000,000 km 2 (9,320,568 mi 2 ) 18,000,000 km 2 (11,184,681 mi 2 ) Average Minimum Areal Extent 7,000,000 km 2 (4,349,598 mi 2 ) 3,000,000 km 2 (1,864,114 mi 2 ) Typical Thickness ~ 2 m (6 n) ~ 1 m (3 n) Geographic Distribu$on Asymmetric Symmetric Snow Thickness Thinner Thicker Trend, Significant decrease of 4.1% (~500,000 km 2 ; 193,000 mi 2 ) per decade Small increase of 0.9% (~100,000 km 2 ; 42,000 mi 2 ) per decade hxp://nsidc.org/seaice/characteris>cs/difference.html
