The End of Upwelling
What a difference a week makes. Late last week, the waters off New Jersey were between 5-15 degrees below normal. They’re not any more.

Satellites vs. Buoys
A little while back, I received the following question from a Visual Ocean visitor: “When might satellite sst data be more informative than buoy data?”
The Ocean in Red, White and Blue
To celebrate Independence Day, I thought it would be fun to dress up the ocean in a little red, white and blue.
Tropical Storm Andrea clouds up the ocean
This week, was the start of the 2013 Hurricane Season, and already forecasters have declared the first storm of the season, Tropical Storm Andrea.
Next Generation Activity Development
Last week, I had an opportunity to look through the Next Generation Science Standards (NGSS) alongside many other ocean educators at the COSEE Network Meeting. Our goal was to figure out how the NGSS could be used to develop activities.
Blog Roundup #1 – Ocean Science and More
I hope to occasionally share some of my favorite web sites and blogs in easily digestible chunks. This first roundup features some of the top sites on ocean, climate and environmental data and science.
Streamflow and Conductance on the Delaware
Conductance is an important measurement of water quality in rivers, and it is often related to river discharge.
RTD Activity Idea: Monitoring Streamflow
The USGS’s National Water Information System provides data that is easily accessible to students, allowing them to investigate real-time river conditions at nearby locations or across the nation.
Streamflow on the Delaware
While temperature, pressure or humidity change with more predictable variation throughout the course of a year, streamflow is more closely correlated with major rain and snow events that occur sporadically throughout the year, often in large doses.
Observations and Forecasts of River Floods
Every time it rains there is a potential for flooding to occur. The National Weather Services’ Advanced Hydrologic Prediction Service (AHPS) analyzes data and models to issue forecasts of potential flooding events.
USGS WaterWatch
Thanks to a network of over 3,000 stream gages monitored by the U.S. Geological Survey, and the WaterWatch web site, we can easily study how rain and snow impact local streams, rivers and estuaries.
Riding the Waves of the Seasonal Roller-Coaster
In the Mid-Atlantic, the winter months usually bring with them strong storms and high winds, and in the ocean, strong winds in the winter lead to larger significant wave heights on average.
