Dense populations of some microscopic algae (phytoplankton) in ocean waters can contaminate seafood, resulting in serious health problems for humans. Satellite data displayed in an online tool help fishermen monitor and avoid these harmful algal blooms.

In this video, students join naturalists who study the large animals found in the estuarine areas of the San Francisco Bay Research Reserve, with special emphasis on native birds.

Students will learn about deep-sea tubeworms. Students will work collaboratively to create a poster or three-dimensional model of a tubeworm. Each group will then prepare a written report describing the anatomy of tubeworms, how a tubeworm obtains food and the symbiotic relationship between the tubeworm and chemosynthetic bacteria, and the role that tubeworms play in the larger cold-seep food web.

As ice retreats and energy resources along Alaska's North Slope become more accessible, diverse stakeholders consider potential futures and develop a science-informed view of the implications of development in the region.

Over the past 40 years, some lobstermen in South Thomaston, Maine, say that they could "set their watches” by the start of the lobster shedding event each season. In 2012, though, extreme warm ocean temperatures—an ocean heat wave—combined with early and repeated lobster shedding. The obvious changes in lobsters during this event galvanized many lobstermen to take the impacts of climate change seriously.

In the Arizona desert, farmers depend on an ample supply of irrigation to grow their crops. As climate changes, irrigation managers face a host of issues to keep the water flowing.

Students will form models of various underwater landform features and create and interpret bathymetric and topographic maps. This curriculum guide outlines three lesson plans that deal with exploration and mapping of the ocean floor.

In the face of a changing climate, the Tribe is building capacity—and climate resilience—through forestry management, habitat protection, and an innovative approach to healthy eating.

This assessment is to be used in conjunction with the lesson "Maigrating Mangroves and Marshes." In this lesson, students will consider climate change's potential impact on mangrove habitats. Activities include researching animals that live in salt marshes and using maps and data sets to investigate habitats and make predictions on how climate change is likely to affect the environmentally diverse mangrove habitat.

Several times per year, seawater floods some of the streets in Charleston, South Carolina. Taking steps to deal with this "nuisance" flooding can help the city prepare for sea level rise.

As Public Works Director of Nogales, Arizona, Alejandro Barcenas works to ensure a safe and secure water supply for the city’s 20,500 residents. His task isn’t easy: the city is located in an arid region just north of the United States–Mexico border, and its entire supply comes from groundwater.

Half of Nogales’ water comes from alluvial aquifers that are highly responsive to rainfall events. Though this convenient source of water recharges easily, it is also vulnerable to climate-related changes such as reduced precipitation and increased evaporation. The other half of the city’s groundwater comes from a lower-quality source—this water is more expensive to produce. To optimize the use of the two sources of groundwater into the future, Barcenas is contributing to the development of a modeling tool that simulates how the aquifers may change in response to climate.

Climate change adaptation isn’t always welcome as a topic of conversation, even among those who could benefit from it. A recent study hints at a possible path forward.

This interactive shows the position of the sun, relative to Earth, as it moves through space.

This interactive helps students understand the role of biodiversity in different regions of the U.S., and how invasive species impact native populations.

This site displays a click-and-zoom map of the US showing forecast temperatures as well as several other meteorological variables, normally updated every hour. Also available are maps showing chance of precipitation, temperature and wind, weather, dew point, weather, precipitation, dew point and cover.

This video shows how Hawaiians use Reduce, Reuse, Recycle, to convert abandoned sea nets to energy.

Reduced flows and increased demand for Colorado River water represent a real and present danger in the West. To address the threat, water managers and modelers initiated a study to understand the system, consider options, and take action.
