ALT A bar chart showing the chance of El Niño (red bars), ENSO-Neutral (grey bars), and La Niña (blue bars) provided for 9 upcoming, overlapping 3-month seasons (each letter represents a month, for example, F = February). The color shading within the bars indicates the chances of different categories of El Niño or La Niña strength (weak, moderate, strong, and very strong). Alternatively, the table at the internet address below presents the percent chances of each strength category in numerical form. https://cpc.ncep.noaa.gov/products/analysis_monitoring/enso/roni/strengths/
ALT Flyer featuring the Choose Your Own (O)Adventure with a QR code, resources provided that include background, classroom ready, and resources by species and region. The bottom of the flyer has a magnifying glass, colored pencils, graph paper, a ruler and a dotted arrow with an arrow showing a generalized path.
ALT A conductivity, temperature, and salinity (CTD) rosette rises from the deep in dark waters at night just below the surface. Water samples from a CTD rosette are used to collect eDNA and then evaluated for species presence and diversity. This information is paired with high-quality measurements of ocean conditions to determine how the environment may affect the distribution of marine life and biological communities. Credit: NOAA

ALT A large mechanical arm lowers down a CTD rosette into calm waters. There is a spotlight highlighting the side of the ship, the arm and rosette. Dim skies are pictured in the distance.
ALT Scientists retrieve a rosette of CTDs, tubes with sensors that measure ocean chemistry and other conditions above calm waters. WCOA 2026 will deploy this tool along the West Coast to assess the status of ocean acidification and its impacts on marine resources. Credit: NOAA
