 Center for Operational Oceanographic Products and Services NOS Fiscal Year 2016 Year in Review  Nuisance Flooding Becomes Part of National Dialogue on Sea Level Rise **Supports NOS priority**: coastal resilience

 In 2016, The Center for Operational Oceanographic Products and Services  (CO-­OPS) provided the second ever outlook for nuisance flooding for the coming  meteorological year. Nuisance flooding was also included as an indicator of  climate change for the first time in the recent Environmental Protection Agency  report, Climate Change Indicators in the United States. Nuisance flooding is recurrent flooding that  takes place at high tide and can cause costly damage to infrastructure. Because  of sea level rise, nuisance flooding in the United States has become a “sunny  day” event – not necessarily linked to storms or heavy rain. The frequency of  nuisance tidal flooding in many U.S. cities increased as predicted for the 2015  meteorological year, from May 2015 to April 2016, and in some cities, the days  of nuisance flooding exceeded trends and broke records, especially in the  southeastern U.S and Gulf Coast. The 2016 outlook expects the nuisance flooding  trend to increase, but takes into account La Niña conditions that typically  have less effect on tidal flood frequencies compared to El Niño. This outlook  can help communities better understand local nuisance flooding frequencies and  prepare for potential impacts.  CO-OPS issued the first report on nuisance  flooding in 2014, analyzing data from NOAA tide gauges where the water level  exceeded the local threshold for minor flooding impacts established by the  local Weather Forecasting Offices of the National Weather Services. CO-OPS  worked with the National Centers for Environmental Information to issue the  Nuisance Flooding outlook.   PORTSR turns 25, Helps Three New Seaports Become More Safe and Efficient **Supports NOS priority**: coastal Resilience

 In 2016,  the Physical Oceanographic Real Time System (PORTSR) held its 25th anniversary and added three  new systems, for a total of 28 PORTSR.  New systems were added in Savannah, Georgia; Cape  Cod, Massachusetts and on the Cuyahoga River in Ohio. These systems provide  real-time, accurate, and reliable observations helping mariners and port  operators to navigate safely, stay on schedule, and maximize cargo loading.  More than 60 of the Nation’s most economically critical seaports are served by  PORTSR.  NOAA has partnered with industry and local maritime  organizations, as well as other federal and state agencies, to install these  systems based on the needs of local mariners and port operators.   CO-OPS Adds Four New Hurricane Hardened Stations in Gulf **Supports NOS priority**: coastal Intelligence

 The Center for Operational Oceanographic Products and Services (CO-OPS) added four new water level stations in the Gulf that are specially reinforced to withstand hurricanes and other major storm events. The reinforced stations are better able to keep functioning during these events, providing critical information on water levels, winds and other meteorological information that can aid emergency response organizations. This was made possible through CO-OPS’ partnership with the Army Corps of Engineers in Galveston, Texas.   CO-OPS Supports California with Analysis and Outreach on Water Levels and Flooding Due to El Nino **Supports NOS priority**: Coastal Resilience
 In December, the Center for Operational Oceanographic Products and  Services (CO-OPS) helped the public in California understand how El Niño was  impacting the water levels on the coast. CO-OPS provided technical guidance and  communication materials to explain how the coastal flooding being seen was  associated with elevated sea level from El Niño. CO-OPS documented the highest  measured tides at eight water level stations throughout California during the  high water level event over Thanksgiving, and released outreach materials  directed at partners to communicate the causes and impacts of these events.  CO-OPS coordinated with the Office of Coastal Management, the National Weather  Service Weather Forecast Office in Eureka, the California coastal management  community, and the Governor's office to provide this support.   NOAA Tide Tables Turn 150 **Supports NOS priority**: coastal intelligence
 William Ferrel and Rollin Harris of the U.S. Coast and Geodetic Survey introduced the Maxima and Minima Tide Predictor, seen here, which began making predictions in 1885

 The Center for Operational Oceanographic Products and Services (CO-OPS)  completed the 2016 Tide Tables and Tidal Current Tables, which marks the 150th  edition since NOAA began publishing them. These predictions are the cornerstone  of the services NOAA provides the nation.  They provide information for  safe navigation for mariners, inform climate change research, help coastal  communities understand when they may experience high or low water, and help  commercial and recreational fishermen improve their catches.  The Coast  and Geodetic Survey, NOAA’s predecessor, published the first edition in  December 1866 for the year 1867. The manuscripts have been shipped to  publishers, and should be available in a few weeks.
