Global number of tide gauges decline due to GPS "week roll over" on 6 April 2019

A number of tide gauges have stopped working due to a US GPS "week roll over" which took place on 6 April 2019. The consequences of the roll over are described in greater details in the Nature article listed below. Some gauges have already stopped and others may stop as they restart in the coming weeks.
The SEA LEVEL STATION MONITORING FACILITY (SLSMF) has been informed by one manufacturer that gauges with certain older loggers will fail
and stop functioning.
The SLSMF will monitor development and it is expected that in the near term the number of operational stations will decline. As of 11 April 2019 the first estimate is that 40 stations have stopped functioning.
