Sea-surface temperature: Negative 0.5 to negative 1.5 (purple): Central Pacific regions. Negative 0.25 to 0.25 (light purple) are in the Arctic and Atlantic Ocean. 0.25 to 2.25 (red) are mostly in the North Atlantic Ocean and South Pacific Ocean.

A composite of sea-surface temperature anomalies during La Niña from November to March during the following years: 1955, 1956, 1965, 1971, 1974, 1976, 1989, and 1999. When sea-surface temperatures in the tropical eastern Pacific drop below normal, it is known as a La Niña event.

A map highlights the principal aquifers across North America, categorized into three types.

Locations of various aquifers in North America, including consolidated rock aquifers, which are made up of mostly volcanic rocks in the Northwest and mostly sandstone and limestone elsewhere; combination aquifers, which are sand and gravel aquifers overlying productive rock aquifers; and productive aquifers, which have a 0.4 liter/second potential

Principal Aquifers

Consolidated rock aquifers, shaded in green, are predominantly found in northern Canada, including regions like Yukon, Northwest Territories, and Nunavut, and extending into parts of British Columbia, Alberta, Saskatchewan, Manitoba, and Newfoundland and Labrador. Also found in the northern Canada regions like Victoria Island, Parry Island, Canadian Arctic Archipelago, and Ellesmere Island, also extending to Southern regions like Winnipeg, Ottawa, and Halifax. Combination aquifers, shaded in orange, are primarily located in the central and eastern United States, covering areas in states like Texas, Oklahoma, Kansas, Nebraska, and South Dakota, and extending to parts of the Midwest, Northeast, and Southeast, including New York, Pennsylvania, and Florida. Productive aquifers, also shaded in light green, are found in regions of Florida and across the western United States near Oregon.
