Document Summary
Pattern of sea level changes relative sea level changes varies regionally. Bedrock is rising as ice sheet retreat. Areas in the ocean where bedrock is sinking due to the added weight of water. Balance between the different movements rocks are behaving elastically and rebounding in these areas. Ocean bedrock sinking and sea level rising impact of ice weight on the sea level floor. With all the water being in glaciers the ocean crus rises. As sea level rises, with the added weight of water the ocean bedrock is sinking and sea level rises due to the added water. Masking the true extent of the sea level rise far away from the ice sheets is where we observe these phenomenon. Rise in sea levels in the 20th century sea level has risen by: 17cm in the last 100 years. Melting of ice from mountain glaciers and ice sheets.
