Alexandrium cyst dormancy (Understanding dormancy requirements and germination of Alexandrium cysts and evaluating cyst mapping as a tool for early warning of harmful algal blooms)

Popis
Blooms of the harmful alga Alexandrium catenella produce potent neurotoxins that accumulate in shellfish, and cause gastrointestinal and neurological symptoms if contaminated shellfish are consumed by humans. The limited predictive capacity for A. catenella blooms poses a significant problem for local managers and shellfish growers and threatens the vitality of the $108 million shellfish industry in Washington State. Shellfish closures due to A. catenella blooms in Puget Sound have increased in frequency, duration, and geographic scope since the 1950s. The short-term goals of this project are to determine the dormancy requirements and germination characteristics of the benthic cyst life stage of A. catenella, and evaluate the effectiveness of traditional cyst mapping as a tool for early warning of bloom events in Puget Sound. The long-term goal is to incorporate this critical information on A. catenella life history characteristics into a model that will provide an unprecedented, powerful risk assessment of toxic blooms in Puget Sound now and in a future warmer climate. This project will determine the mandatory dormancy period of Alexandrium cysts (i.e. time from cyst formation until cysts can germinate) from Puget Sound and whether or not cysts display secondary dormancy. Secondary dormancy is a phenomenon that prevents germination during periods that are actually favorable for germination, but not for growth. These datasets will describe and better explain temporal patterns in cyst germination.

This georeferenced image represents 5 meter resolution bathymetry (sun illuminated with azimuth 225 and incline 45) of the south shore of St. John, US Virgin Islands. NOAA's NOS/NCCOS/CCMA Biogeography Team and NOAA/NOS/OCS/HSD personnel, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in the US Virgin Islands from 2/18/04 to 3/5/04. Data was acquired with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz) and processed by a NOAA contractor using CARIS HIPS v5.4 software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides from NOAA COOPS. Data is in UTM zone 20 north, datum WGS84. The processed CARIS data was used to generate a CARIS BASE surface -akin to a DTM- based on swath angle with footprint size 3*3. Within CARIS, an imagery file with associated georeferencing was then exported from the BASE surface. While the project was conducted to meet IHO Order 2 accuracy standards, there is a roll artifact (averaging 0.5m high) in the dataset that the user should take into consideration when performing any analysis.

The long-term goal is to incorporate this critical information on A. catenella life history characteristics into a model that will provide an unprecedented, powerful risk assessment of toxic blooms in Puget Sound now and in a future warmer climate. This dataset describes the viability of cysts (i.e. their ability to germinate given optimal conditions in the laboratory) from approx 40 locations throughout Puget Sound. This information will be used to modify traditional cyst mapping to better understand how this risk factor is related to bloom potential.
