Tides are the regular rise and fall of the sea surface caused by the gravitational pull of the moon and sun and their position relative to the earth. There are some factors we can predict that cause the tides to be higher or lower than what is "normally" seen from day to day. Our bulletin tells you when you may experience higher than normal high tides around the nation for December 2016 through February 2017.
La Niña means The Little Girl in Spanish. La Niña episodes represent periods of below-average sea surface temperatures across the east-central Equatorial Pacific. Global climate La Niña impacts tend to be opposite those of El Niño impacts. In the tropics, ocean temperature variations in La Niña also tend to be opposite those of El Niño. During a La Niña year, winter temperatures are warmer than normal in the Southeast and cooler than normal in the Northwest.
It's time for the next installment in the Ocean Today "Full Moon" series. Are you ready to talk trash and protect the sea from marine debris? This full moon we are excited to share with you the Regional Emmy® award-winning TRASH TALK special feature, a hands-on activity demo, and bonus content. This series explores the impacts and causes of marine debris with a science and solution driven approach that is fun, timely and useful. Don't you think it's time for us to have a TRASH TALK?
"Coral reef ecosystems will change as a result of the pressures they are under, but nature perseveres. Efforts to move the needle of conservation in a positive direction will take creativity, commitment, endurance, dedication, and community engagement. The steps we take today to address the threats they face, restore habitat and further the science that fuels effective conservation, will ultimately give these amazing ecosystems a fighting chance." — NOAA Coral Reef Conservation Program Director
