Who youre also listening to from St.Johns

George Rose , Scientific Director ofCFER

Led 2011 mission, will lead 2012,2013 missions

Expertise in fisheries, acoustics,oceanography; long track-record ofsuccess led to establishment of CFERin 2010

What is the Centre for Fisheries EcosystemsResearch?

Established in July 2010 with major funding from the Government ofNewfoundland and Labrador

focus on fisheries ecosystem science with the goal of ensuring that ourfisheries be sustainable for future generations

55% of the support allocated to staff and inshore research; 45%allocated to chartered vessel time

In October 2010, the Marine Institute chartered the RV Celtic Explorerfrom the Irish Marine Institute for offshore and trans-Atlantic surveys(2011-2013)

Fortuitous timing for potential collaboration with Euro-BASIN

Survey the biomass and age-size structure of overwinteringcod within Newfoundlandwaters

Collect otoliths for ageing and

studies of cod distribution andmovements via microchemistry

Collect cod stomachs andtissue samples for isotopeanalyses to determine feeding

Study the impact of a fisheryclosed area on the distributionand abundance of fish andcrustaceans

Collect oceanographic data Listen for cod tagged with

active transmitters (CanadianDFO) Collect acoustic (fish-

plankton), CPR (plankton),oceanographic, and seabirdand whale data across theNorth Atlantic

Provide a training platform forgraduate students

CFER has a total of 4 more trans- Atlantic crossings scheduled (2012,2013)

Our colleagues in Ireland areplanning some additional

oceanography on our 2012 trip andwill be funding that (still in planningstage) and we will be working closelywith them on this and other aspects ofthe research. Although our focus is onthe continental shelf fisheries, we doneed to get a better handle on thewhole North Atlantic ecosystem (it isn'tall continental shelf).

18/19

at the moment at least we should be listed as basin-independent activities, but of common interest; but we areinterested in as close a collaboration as we can.

we are open to modifying what we do on the crossingsif it will benefit an overall research effort. We areparticularly interested in oceanography, the acoustics ofthe mesopelagic (deep scattering layer) and concurrentdistributions of marine mammals and seabirds.

19/19

Lessons learned by CFER in 2011 and possiblepoints of discussion 2011 late winter crossing was rough and limited surveyed

area future surveys will be in late Spring (should still seecod aggregations)

2011 data suggest interesting trans-Atlanticoceanographic and species distribution patterns

The duration of trans-Atlantic crossings appear to differbetween CFER and Euro-BASIN

2012, 2013 CFER trans-Atlantic objectives remain flexible CFER has an interest in international collaborations
