2.1 Introduction to Indicator
-
Phytoplankton are key biological regulators of the structure and function of most marine ecosystems. They are the foundation of the marine food web and are the primary food source for zooplankton and filter feeders such as shellfish. Numerous environmental and oceanographic factors interact to drive the abundance, composition, spatial distribution, seasonal timing and productivity of phytoplankton. Satellite derived measurements of chlorophyll, the dominant photosynthetic pigment in phytoplankton, are used to estimate total phytoplankton biomass. The size structure of the phytoplankton community influences important biogeochemical and ecological processes, including transfer of energy through the marine food web. Phytoplankton growth depends on the availability of carbon dioxide, sunlight and nutrients and their growth rates can be influenced by water temperature, water depth, wind, and grazing pressure. Primary productivity is a measure of the amount of carbon produced by phytoplankton.

Primary productivity is a measure of the amount of carbon produced by phytoplankton.
The unique physical characteristics of the Northeast U.S. continental shelf help make it among the most productive continental shelf systems in the world influenced by both bottom-up (e.g. nutrient concentrations, light availability, and mixing/stratification) and top-down (e.g. grazing) controls. Phytoplankton biomass, composition, and productivity all have high spatial, seasonal and interannual variability. The most pronounced spatial pattern is the decrease in phytoplankton biomass from the coast to the shelf break. Georges Bank and Nantucket Shoals are shallow regions that are well mixed by tides. This mixing supplies sufficient nutrients to support phytoplankton growth throughout the year. In other regions, blooms of large diatom species occur on a seasonal cycle when growing conditions are ideal.
2.2 Key Results and Visualizations
-The seasonal cycles of phytoplankton size distribution are typically dominated by larger-celled microplankton during the winter-spring and fall bloom periods, while smaller-celled nanoplankton dominate during the warmer summer months. In 2023, MAB total chlorophyll was below average in early spring, near average through the summer and above average throughout the fall. A peak in primary production occurred in summer, followed by an above average productivity associated with the early fall bloom. Phytoplankton size class distributions were near average for most of the year, except during the early fall bloom.
-Total chlorophyll concentrations on Georges Bank were above average for most of the year. The early winter bloom was most likely associated with diatoms, however the above average chlorophyll, primary production and microplankton fraction from April through August can be attributed to the dinoflagellate Tripos muelleri.
-Total chlorophyll concentrations in the Gulf of Maine were above average for most of the year. The early winter bloom was most likely associated with diatoms, however the record high chlorophyll, primary production and microplankton fraction from April through August can be attributed to the dinoflagellate Tripos muelleri.

There is high interannual variability of the seasonal phytoplankton cycle. At the monthly scale, MAB chlorophyll and primary production are increasing during January and there has been a decrease in September chlorophyll, likely due to extension of the summer stratification and delayed fall turnover. Fall and winter chlorophyll and primary production are increasing on Georges Bank and Gulf of Maine.

The Gulf Stream was highly variable throughout the year, with northward shifts intermittently throughout the year and a more notable prolonged shift north along the continental shelf break in the southern Mid-Atlantic in the fall [Fig .]. This shift severely constricted the Slope Sea, the waters between the Gulf Stream and continental shelf. This shift also inhibited formation of western warm core rings and limited warm core ring interactions at the continental shelf break. The position of Gulf Stream near the continental shelf break resulted in unusually warm and salty surface waters with strong northeastward currents in the southern Mid-Atlantic in October. The warm waters are a threat to temperature sensitive species, particularly those that are at the southern end of their range or are not mobile (e.g. scallops), while also providing suitable habitat for more southern species.

-{width=100%}
While the total number of 2023 warm core rings (18) was below the decadal average (31), there were a few events worth noting. A large early season ring moved along the shelf break and created an anomalously large shelf streamer that pulled continental shelf water into the Slope Sea. Additionally, when warm core rings interact with the shelf break, they can create biological hotspots. Hotspots can aggregate multiple species in small areas, increasing bycatch risks and marine mammal shipstrike risks. In spring 2023, concentrations of North Atlantic right whales, humpback whales, basking sharks, and other large baleen whales were observed feeding near the edge of two warm core rings that were adjacent to the continental shelf break.
Multiple fall 2023 tropical and coastal storms caused several flash flood events, above average coastal water levels, strong winds and high rainfall totals throughout the Northeast. These storms are potentially linked to the transition from the 2020-2022 La Niña conditions to strong El Niño conditions in late spring 2023. During El Niño winters, there is a noted increased frequency of East Coast storms. Storms increase the risk of coastal flooding and freshwater runoff into the coastal ocean, affect both commercial and recreational fishing, and can delay the spring transition from a well mixed water column to stratified. Increased freshwater flow decreases salinity in estuaries, reducing the amount of suitable estuarine habitat for juvenile marine fish species. In estuaries, hypoxia (low oxygen) also tends to be more severe in wet years, which negatively impacts habitat quality. The current El Niño is expected to gradually weaken and transition to neutral conditions in spring 2024.
55.2.0.2 Regional/Coastal Phenomena
There was a documented die-off of scallops in the Mid-Atlantic Elephant Trunk regions between the 2022 and 2023 surveys. In 2022, Elephant Trunk experienced stressful temperatures for scallops (17 - 19 ℃) for an average of 30 days, but ongoing research is being conducted to identify contributing factors. In summer 2023, a fish and shellfish mortality event was observed in coastal New Jersey linked to hypoxia (low dissolved oxygen) and ocean acidification.

Summer bottom temperatures in the Gulf of Maine were the warmest on record (since 1959) resulting in the second largest bottom marine heatwave. The heatwave started in February, peaked in May and likely continued beyond August (pending data update). 2023 bottom temperature exceeded the 15oC threshold for up to 59 days along the shelf break. Data are not available yet to determine the primary source water into the Gulf of Maine nor, the impact of the fall Gulf Stream position on the bottom temperatures in the Gulf of Maine.
A wide-spread, long-duration phytoplankton bloom of the dinoflagellate Tripos muelleri generated record high (since 1998) chlorophyll concentrations that were up to ten times greater than average. The bloom was observed throughout the Gulf of Maine from March to August and extended onto Georges Bank and the northern Mid-Atlantic Bight (Fig. ). The bloom severely reduced water clarity, impacting harpoon fishing and likely affecting visual predators. Blooms of large phytoplankton species such as diatoms (20-200 µm) are a primary source of energy to the system. However, despite the size of Tripos (100-200 µm), initial observations indicate that the bloom was not grazed, nor did it sink to the bottom. The specific drivers of the bloom and implications to the food web are still under investigation.

In Chesapeake Bay, hypoxia conditions were the lowest on record (since 1995), creating more suitable habitat for multiple fin fish and benthic species. Cooler Chesapeake Bay water temperatures paired with low hypoxia in the summer suggest conditions that season were favorable for striped bass. Cooler summer temperatures also support juvenile summer flounder growth. However, warmer winter and spring water temperatures in the Chesapeake Bay, along with other environmental factors (such as low flow), may have played a role in low production of juvenile striped bass in 2023. Higher-than-average salinity across the Bay was likely driven by low precipitation and increased the area of available habitat for species such as croaker, spot, menhaden, and red drum, while restricting habitat area for invasive blue catfish.

At the monthly scale, MAB chlorophyll and primary production are increasing during January and there has been a decrease in September chlorophyll, likely due to extension of the summer stratification and delayed fall turnover. Fall and winter chlorophyll and primary production are increasing on Georges Bank and Gulf of Maine.
+The seasonal cycles of phytoplankton size distribution are typically dominated by larger-celled microplankton during the winter-spring and fall bloom periods, while smaller-celled nanoplankton dominate during the warmer summer months. Phytoplankton size class distributions were near average for most of the year, except during the early fall bloom.
+On Georges Bank, the early winter bloom was most likely associated with diatoms, however the above average microplankton fraction from April through August can be attributed to the dinoflagellate Tripos muelleri.
+In the Gulf of Maine, the early winter bloom was most likely associated with diatoms, however the record high microplankton fraction from April through August can be attributed to the dinoflagellate Tripos muelleri.
