Collaborative Research: Zooplankton restarts in a high-latitude marine ecosystem: species-specific recruitment and development in early spring https://osprey.bco-dmo.org/project/908803 Collaborative Research: Zooplankton restarts in a high-latitude marine ecosystem: species-specific recruitment and development in early spring <p><strong>NSF Award Abstract</strong><br /> Global climate change and associated extreme weather events are increasingly impacting marine communities at all trophic levels and leading to shifts in the timing of life history events. This project is investigating the annual restart of the spring zooplankton community in the Gulf of Alaska in order to determine the timing of species-specific recruitment and growth. Zooplankton are small pelagic animals that are a critical link between microalgae and protozoans and higher levels in the food web including economically important fishes, birds and marine mammals. While their abundances and species composition have been documented over part of the annual cycle between late spring and fall, this project focuses on winter and early spring. The project integrates traditional methods with modern molecular approaches to characterize the diversity, development, feeding and physiology of zooplankton, especially the early developmental stages of copepods (small crustaceans). The goal is to determine which species are there, how many are present and where they are in the water column, and to reveal indicators of their health. Broader impacts include research training for three graduate students and at least four undergraduates in biological oceanography and physiological ecology. Outreach activities are focusing on broadening the public’s understanding of plankton ecology. An illustrated zooplankton guide for the Gulf of Alaska and plankton module for school teachers and students is being produced in collaboration with the Center for Alaskan Coastal Studies. Other plans include sponsorship of nature-drawing workshops on zooplankton and the production of an Art &amp; Science traveling exhibit.</p> <p>This project is tracking zooplankton population abundances, species composition and developmental stages through the spring restart in a high-latitude fjord in the northern Gulf of Alaska. While the entire zooplankton community is being characterized, the main focus is on the difficult-to-assess early developmental stages of copepods, which dominate the late spring biomass in the region. Three central hypotheses guide the research: 1) high abundances of copepod nauplii are present before any measurable increases in food in surface waters; 2) species diversity increases between winter and spring, with nauplii from large lipid-rich capital-breeding species appearing first, followed by those from income- and hybrid-strategy species and finally nauplii that emerge from dormant eggs; 3) prior to the appearance of food resources, nauplii from capital-breeding species conserve resources by delaying development and entering a state of dormancy in the second and third naupliar stages. The project entails intensive depth-stratified field sampling to characterize the wild community, in combination with laboratory experiments on nauplii to determine their responsiveness to food. The prey are being characterized by measuring chlorophyll a, dietary and prey community DNA sequencing and flow cytometry to establish diversity and abundances. Size-fractionated zooplankton samples are being analyzed using microscopy and community DNA sequencing to ascertain species diversity, developmental stage distribution and abundances. Feeding activity is being measured using dietary DNA sequencing of nauplii followed by comparisons with the prey field. Dormancy in nauplii is being determined by differential gene expression of target genes (RT-qPCR) and high-throughput sequencing of mRNA of individuals (transcriptomics) and community samples (meta-transcriptomics). Short-term and long-term effects of food availability on dormancy, development and growth are being quantified in laboratory experiments. Broader impacts are focused on training of students in interdisciplinary research and state-of-art techniques, and public outreach to introduce plankton ecology to broader audiences.</p> Zooplankton recruitment largerWorkCitation project eng; USA oceans -149.3583 -149.3583 60.025 60.025 2023-01-05 2023-03-24 Sub-arctic marine ecosystem, Gulf of Alaska 0 BCO-DMO catalogue of parameters from CTD (temperature, salinity and fluorescence) from bi-weekly vertical profiles in Resurrection Bay, AK from January to March of 2023 Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact http://lod.bco-dmo.org/id/dataset-parameter/958893.rdf Name: cruise Units: unitless Description: <p>Cruise ID </p> http://lod.bco-dmo.org/id/dataset-parameter/958894.rdf Name: station Units: unitless Description: <p>Station ID</p> http://lod.bco-dmo.org/id/dataset-parameter/958895.rdf Name: date_local Units: unitless Description: <p>Date (Local time, Alaska Standard Time) in ISO 8601 format yyyy-mm-dd</p> http://lod.bco-dmo.org/id/dataset-parameter/958896.rdf Name: start_time_local Units: unitless Description: <p>Time (Local time, Alaska Standard Time) formatted as hh:mm and 24-hour clock</p> http://lod.bco-dmo.org/id/dataset-parameter/958897.rdf Name: start_DateTime_UTC Units: unitless Description: <p>Start DateTime with timezone (in UTC, ISO 8601 format)</p> http://lod.bco-dmo.org/id/dataset-parameter/958898.rdf Name: julianday Units: unitless Description: <p>Intiger Day of Year (1=Jan 1st)</p> http://lod.bco-dmo.org/id/dataset-parameter/958899.rdf Name: lat Units: decimal degrees Description: <p>Station latitude, north is positive</p> http://lod.bco-dmo.org/id/dataset-parameter/958900.rdf Name: lon Units: decimal degrees Description: <p>Station latitude, west is negative</p> http://lod.bco-dmo.org/id/dataset-parameter/958901.rdf Name: binned_pressure Units: Decibars (dbar) Description: <p>Pressure (dbar) binned at 1 dbar intervals</p> http://lod.bco-dmo.org/id/dataset-parameter/958902.rdf Name: temperature Units: Celsius (C) Description: <p>Water column temperature</p> http://lod.bco-dmo.org/id/dataset-parameter/958903.rdf Name: conductivity Units: Siemens per meter (S/m) Description: <p>Water column conductivity</p> http://lod.bco-dmo.org/id/dataset-parameter/958904.rdf Name: turbidity Units: Nephelometric Turbidity Unit (NTU) Description: <p>Water column turbidity </p> http://lod.bco-dmo.org/id/dataset-parameter/958905.rdf Name: fluorescence Units: Milligrams per cubic meter (mg/m^3) Description: <p>Water column chlorophyll-a fluorescence </p> http://lod.bco-dmo.org/id/dataset-parameter/958906.rdf Name: time_elapsed Units: Seconds (s) Description: <p>Time elapsed from instrument initialization</p> http://lod.bco-dmo.org/id/dataset-parameter/958907.rdf Name: scan Units: unitless Description: <p>Scan count</p> http://lod.bco-dmo.org/id/dataset-parameter/958908.rdf Name: depth Units: Meters (m) Description: <p>Depth of CTD in water column. </p> http://lod.bco-dmo.org/id/dataset-parameter/958909.rdf Name: salinity Units: Practical Salinity Units (PSU) Description: <p>Water column salinity</p> http://lod.bco-dmo.org/id/dataset-parameter/958910.rdf Name: sigmaT Units: Kilograms per cubic meter (kg/m^3 ) Description: <p>Water column density</p> http://lod.bco-dmo.org/id/dataset-parameter/958911.rdf Name: descent_rate Units: Meters per second (m/s) Description: <p>Descent rate of instrument package</p> http://lod.bco-dmo.org/id/dataset-parameter/958912.rdf Name: nbin Units: unitless Description: <p>Number of scans averaged over 1 db bins.</p> GB/NERC/BODC > British Oceanographic Data Centre, Natural Environment Research Council, United Kingdom Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact 293278 https://darchive.mblwhoilibrary.org/server/api/core/bitstreams/eb1921dd-f2a9-4d07-868f-ca264c8819a5/content download https://doi.org/10.26008/1912/bco-dmo.954156.1 download onLine dataset &lt;p&gt;Samples were collected in Resurrection Bay within the inner basin at RES2.5 (60° 1.5’ N, 149° 21.5’ W; 298 m deep) at approximately biweekly intervals aboard the R/V Nanuq between January 5th and March 24th, 2023.

All SBE 25s can also operate in real-time, transmitting data via an opto-isolated RS-232 serial port. Temperature and conductivity are measured by the SBE 3F Temperature sensor and SBE 4 Conductivity sensor (same as those used on the premium SBE 9plus CTD). The SBE 25 also includes the SBE 5P (plastic) or 5T (titanium) Submersible Pump and TC Duct. The pump-controlled, TC-ducted flow configuration significantly reduces salinity spiking caused by ship heave, and in calm waters allows slower descent rates for improved resolution of water column features. Pressure is measured by the modular SBE 29 Temperature Compensated Strain-Gauge Pressure sensor (available in eight depth ranges to suit the operating depth requirement). The SBE 25's modular design makes it easy to configure in the field for a wide range of auxiliary sensors, including optional dissolved oxygen (SBE 43), pH (SBE 18 or SBE 27), fluorescence, transmissivity, PAR, and optical backscatter sensors.

A beam of light is shown through a water sample. The turbidity, or its converse clarity, is read on a numerical scale. Turbidity determined by this technique is referred to as the nephelometric method from the root meaning "cloudiness". This word is used to form the name of the unit of turbidity, the NTU (Nephelometric Turbidity Unit). The meter reading cannot be used to compare the turbidity of different water samples unless the instrument is calibrated.
