Wobbly Sea Level Rise: U.S. East Coast (VI)

I’ve been looking more closely at the result from my new alignment method for tide gauge data, applied to the U.S. east coast. In particular, I’ve been studying the data since 1950, which very nearly follows a straight line:

Sea Level Rise: U.S. East Coast (IV)

The 2nd region in my set of U.S. east coast areas (as part of the ongoing series) is the Mid-Atlantic North (MAN), from New York City down almost to Cape Hatteras:

Sea Level Rise: U.S. East Coast (III)

I’ll alter course in my cursory look at four regions of the U.S. east coast (we already looked at New England) to comment on a few things mentioned in comments.

Sea Level Rise: U.S. East Coast (II)

In the last post I defined the four regions of the U.S. east coast for which I’ve created a regional sea level estimate (since 1950). Northernmost is my New England (NE) region, which includes the coasts of Rhode Island and … Continue reading

Sea Level Rise: U.S. East Coast (I)

A new paper by Piecuch et al. looks at how sea level rise has differed from place to place along the east coast of the U.S. There’s a nice write-up about it in Science Magazine.

Sea Level Stations with a Long Record

Tide gauges measure local sea level, the difference between sea surface height (SSH) and the height of the land. If the sea surface gets higher — what we usually think of as “sea level rise” — local sea level won’t … Continue reading

Sea Level Change on the U.S. East Coast, part 2

A tide gauge doesn’t measure the height of the sea surface; rather it measures the difference between the height of the sea and the that of the land. Thus is it sensitive to changes in sea surface height (SSH), and … Continue reading

Recent Sea Level Change

NOAA provides an excellent website for acquiring and examining sea level data from tide gauges. It includes maps with which one can select individual stations, but which also show the rate of sea level rise based on fitting a linear … Continue reading

Rising Sea

Not long ago Watson et al. compared satellite sea-level data to estimates from tide gauges. They concluded that the satellite data show systematic drift, which is satellite-specific, most strongly affecting the first six years’ observations.

What is sea level up to lately?

Since 1993 we’ve been monitoring sea level with satellites. The overall rise is obvious (it was obvious even before 1993), and we now know that the rate of rise is faster than it has been in a very very long … Continue reading
