On Thin Ice
Hypothesis and background

Sea ice is a dominant feature of marine ecosystems in the Arctic. Its presence directly
or indirectly mediates many of the physical, chemical, and biological processes of
Arctic marine ecosystems, especially on the shelves where benthic and pelagic
systems are extensively coupled. Ice is also one of the features of the Arctic seas that
are most profoundly affected by local, regional, and global climate, varying on scales
ranging from days to millennia. Therefore, sea ice can be seen as a lever through
which changes in climatic regimes can have far-reaching consequences on the
structure and function of Arctic marine ecosystems.
Using this rationale, we aim to test the hypothesis that changing ice conditions
associated with different climatic regimes drives primary production on the northern
Svalbard shelf through different dominant sources (ice algae vs. phytoplankton). We
propose that such variation in the dominant source pathways of primary production
has concomitant effects on both the pelagic and benthic systems, as well as the trophic
pathways by which they are coupled. We will use field measurements and laboratory
analyses to test a series of working hypotheses related to the primary producers,
zooplankton, and benthic components in a region of the northern Barents Sea near
northeast Spitsbergen. In this region, sea ice varies on small spatial and temporal
scales during the biologically active portion of the year (Arctic spring and summer)
and an unusually high benthic biomass supports an extensive shrimp fishery and a
large local population of walrus.
Ultimately, this study aims to provide some insight into the energetic pathways and
trophic structure of this ecosystem and its stability versus sensitivity in the face of
predicted future climate changes. International policy-making bodies (e.g.
Whitehorse Declaration, Arctic Climate Impact Assessment) recognize that such an
ecosystem-based approach to assessing effects of climate change is the most effective
means to understand the possible consequences of climate change to biotic systems.

Flame retardants Integrated Risk assessment for Endocrine effects Risk Assessment of
Brominated Flame Retardants as Suspected Endocrine Disrupters for Human and
Wildlife Health
Supported by the European Commission, 5th Framework programme for research,
technological development and demonstration activities, first activity, Quality of Life

Overall objectives
      The overall objective of this multi- and interdisciplinary project is to improve
risk assessment of brominated flame retardants (BFRs) for human health and wildlife.
BFRs, such as the high production volume chemicals polybrominated diphenyl ethers
(PBDEs), tetrabromobisphenol A (TBBPA) and hexabromocyclododecane (HBCDD)
have been identified as potential endocrine disrupters. PBDE levels have been steadily
increasing in biota over the last decades. Using in vitro cell systems of particular
relevance for endocrine effects, BFRs will be selected for rodent and fish toxicity
studies with emphasis on endocrine and immune system. After further selection,
reproduction studies in the rat (with neurobehavioral and immune function tests) and
partial life-cycle assays in zebrafish will be carried out. The exposure part includes
congener specific identification, regional distribution and temporal trends of BFRs in
tissue of wildlife and fish, human milk and diet within the EU. By integrating
information on exposure, fate and toxicity this project aims a highly significant
contribution to integrated risk assessment for humans and aquatic environment with
respect to endocrine disruption by BFRs.

Objective concerning NTNU involvement in FIRE - project
     Human and aquatic wildlife exposure assessment: For the aquatic wildlife
exposure assessment (WP7, 8, 10), information will be obtained on i) the food chain
transfer of BFRs from water, sediment to invertebrates to predators (fish) and fish-
eating top-predators (tern, seal and polar bear), ii) temporal trends, iii) environmental
transformation (WP8). A predictive food web model will be developed (WP10). For
the food chain transfer (WP7) samples will be collected at different levels of BFR
pollution exposure in the marine environment, estuaries and freshwater locations.
Reference sites will be Arctic. Oslofjord and Froan (Norway) and more polluted
locations will include The Netherlands (close to a BFR production plant as well as the
Wadden Sea), UK (Clyde and Mersey), France (Seine estuary), Germany (Elbe) and
Czech Republic (Elbe). BFRs (e.g. PBDEs, HBCD and TBBPA) will be determined
and an interlaboratory study will be conducted between the laboratories that perform
the BFRs analysis. Temporal trends of BFRs in aquatic wildlife will be investigated
using harbour seal samples of a time period of the last 10 years, and dated sediment
cores collected in one area of the fish-eating bird species (WP 7). In WP8
environmental transformation reactions of BFRs in the abiotic system (UV-
irradiation) and biotic system (micro-organisms and microsomal systems of fish,
birds, and marine mammals (e.g., harbour seals) will be studied. On the basis of the
aquatic food chain transfer and environmental transformation data, a predictive food
web model of BFRs in abiotic environment to the top-predators will be developed
(WP10). WP9 is strongly linked to both human (WP6) and aquatic wildlife exposure
(WP7, 8) and should provide information on the contribution of the levels of BFRs
from human and wildlife samples to the total in vitro endocrine disrupter response.

Lance-voyage :
     Sample invertebrates and fish for analysis of BFR's and d15N og d13C (to
determine trophic level). If Atlantic Cod is available blood will be samples for
analysis of biomarker responses. The following species is aimed to be samples; high
priority; Calanus spp, Euphausiids spp, bentic invertebrates (one or two speices),
polar cod (pelagic fish), Atlantic cod and/or other species of bottom-dwelling fish.
Amounts required; fish - 10-25 specimens (adults) and invertebrates more than 200
gram of each speices.
Digestibility of ice algae and phytoplankton: The
potential impacts of changing food supply to the
arctic benthos
Funded jointly by the Norwegian Research Council and the U.S. National Science
Foundation. Akvaplan-niva is the coordinator of Norwegian participation, with
several U.S institutes represented (East Carolina University, Bates College, University
of Georgia, and State University of New York Stoneybrook).

Project Summary
In Arctic marine ecosystems, primary production is partitioned between ice algae and
phytoplankton. Reduced thickness and extent of sea ice associated with climatic
shifts will likely lead to changes in the relative proportions of these two components
to total primary productivity. There are potentially significant implications of such
changes to benthic communities, which are totally dependent upon sedimenting
organic matter from the overlying water column for their energetic requirements. To
date it has been assumed that because both ice algae and phytoplankton are dominated
by taxonomically similar species (e.g. diatoms and flagellates), both sources of food
are identical in quality. Several indirect observations challenge this assumption.
However, the comparative roles of ice algal- and phytoplankton-derived organic
matter to the energetics of benthic species and communities has never been
quantitatively addressed. We propose to investigate whether there are differences in
the digestability of ice algae and phytoplankton-derived organic matter to Arctic
benthos. We have designed a series of ship-board and land-based experiments to
identify patterns of differential selection, absorption, and assimilation of ice algae and
phytoplankton on whole benthic communities and selected dominant taxa, and we will
carry out simultaneous, identical experiments in Svalbard and Alaska in order to
assess whether results are region-specific or pan-Arctic in nature. This project has
been designed to compliment and derive synergistic benefits from the goals and
workplan of the Thin Ice project and an ongoing NSF project in Kotzebue, Alaska.


The overall goal of the project is to assess the quality of ice algae (two types) and
phytoplankton as food sources for the arctic benthos.

Digestibility includes three components, all of which will be experimentally tested during the
course of the project: 1) selection (is encountered organic material consumed or rejected?); 2)
absorption (is ingested organic material absorbed during passage through the gut, or is it
egested in the feces?); and 3) assimilation (is absorbed organic material assimilated into

Goals and Workplan for the Lance cruise

The digestibility work for the autumn 2003 will focus on the short term absorption of
ice algal and phytoplankton-based material to selected benthic macrofauna. Two
main techniques will be employed: (1) Ash-ratio method to measure absorption
efficiency and (2) Pulse-chase radiotracer (14C) method to measure carbon retention
efficiency. The ash ratio method will also be employed to measure integrated
absorption efficiency of the whole benthic community.
List of participants shall be delivered to the captain before departure
    Name of participants
    Name of next of kin for each participant
    Next of kin address
    Next of kin daytime and night-time telephone number

Safety on board
Safety briefing will be given by the ships officer when we leave the harbour.
Emergency exits, life boats, fire equipment etc

Weapons and Polar Bears
Instruction and shooting training by Haakon Hop

Ships safety
The safety of the ship will always be the captain’s responsibility. He therefore has full
rights to deviate from the cruise plan if visibility, weather, ice conditions or other
circumstances should compromise the ship’s safety.

Personnel safety
The safety of the personnel onboard is the responsibility of the captain. Cruise
participants should therefore always follow any directions given by the officers. When
putting parties ashore, the captain is responsible for the transport to and from the
shore, and he has the right to postpone or cancel this operation if he finds the
conditions unacceptable.
During helicopter transport, the pilot is responsible for personnel safety.
The cruise leader is responsible for the safety of people ashore. Guns with sufficient
stopping power should always be brought ashore with every group for protection
against polar bears. Handheld VHF-communications is recommended for
communication between groups ashore, and between shore parties and Lance. VHF-
radios are available on Lance for this use.

Persons with heart conditions or other serious illnesses should consult their doctor
before participating on the cruise.

Allergy, special food requirements
If there are vegetarians or people with food allergies among the participants, this
should be communicated as soon as possible to give the ship time to get the necessary
provisions. The ship can accommodate most such needs provided they are given this
information in advance.
Cruise report
The cruise report should be ready at the end of this cruise

The report should be approx. 10 pages and consists of a data log where the daily
activity are logged and a short report for each sub activity. Each activity should be
described one a page and contain tables of the samples taken. Where and how the
sampled are stored should be noted and planed analyses. The following sub-activity
are suggested,

      Physical oceanography and ice-characteristics
      Ice fauna and diving operations
      Zooplankton
      Benthos
      Phytoplankton and ice algae
      Brominated flame retardants (BFRs) and the FIRE project
Daily routines
We will follow the watches, dinner times and routines of the ship

A daily meeting will be held around 2100:
    Discuss the results of last days work
    Plans for the next day
    Safety and other matter
    Daily talk (scientific, slide show or other informative talks)

All participants has to give a talk about their project
Scientist and students are asked to give additional talks a scientific
team of interest
Overall time schedule
This plan will be modified and updated daily dependent on progress with sampling,
weather and ice conditions.

Steaming from LYR to Kongsfjorden

Kongsfjorden ( 10-11 August and 4-5 September)
Environmental parameter (all station):
Water samples for phytoplankton/chlorophyll
Multi Plankton Sampler
Additional CTD-stations shall be taken close to SAMS mooring as specified by
Finlo Cottier. N 78 58.307 E 011 39.11 (260m depth) Close to "Stuphallet" shore. However, there
is a subsurface pellet quite close to the surface so it's better not to go too close. If there are suitable
resources aboard (i.e. the manpower)perhaps you could fire bottles at depths 0m, 10m, 20m and 30m
and process them for Chlorophyll.

Lipase activity
Lipase assay procedures
Lipases can be viewed both as lipolytic and esterolytic activity enzymes, being
catalysts for a large numbers of esters. The activity of lipases can thus be assayed by
monitoring the release of either fatty acids or glycerol from triacylglycerols or fatty
acid esters. Further, since lipase acts at the oil/water interface, change in the
properties of the interface is an important criterion for measuring lipolysis.
Estimation of released fatty acid
The fatty acids released by lipase-mediated hydrolysis can be determined qualitatively
by gel-diffusion assay and quantitatively using a) colorimetric assays, b)
chromatography procedures (TLC/HPLC).
Qualitative methods: Lipase-producing strains from a wide population are
conventionally screened on agar plates supplemented by Tween 20. A zone of Tween
20 hydrolysis is indicative of both esterase and lipase activity. More recently, agar
plates supplemented with olive oil have also been employed for screening lipase-
positive colonies. Agar plates, supplemented with lipids from Copepods, could be a
very useful tool for screening lipase activity using Psychrobacter sp. TAD1 as
bacterial strain. The presence and the diameter of the aloe during bacterial growth
may demonstrate the capacity of this strain to degrade natural fatty acids.
Quantitative methods: The lipolytic activity demonstrated on natural fatty acids will
be quantified utilising, colorimetric assays and chromatography procedures.
