Alaska plaice and yellowfin sole were collected during the 2007 # and 2008 RACE summer bottom trawl surveys, respectively. Yellowfin sole and northern rock sole are relatively abundant and targets of # important commercial fisheries, while Alaska plaice is a less common bycatch species. All three species can reach a maximum age of over # 30 yr, and possess otoliths with relatively clear annual growth increments. # # Otoliths were sectioned transversely through the core and burned over an alcohol flame to increase contrast between seasonal (translucent # and opaque) growth zones. One complete annual increment (annulus) was defined as the combination of one translucent and one opaque growth zone. # Otoliths were photographed, visually crossdated to ensure the correct calendar year was assigned to each annulus, and annuli were measured # using the imaging software Image-Pro Plus v.5.1. Visual crossdating was verified using the International Tree-Ring Data Bank Program Library # quality-control software COFECHA using 22-year 50% frequency cutoff cubic splines. A master chronology was then generated for each species # by fitting each otolith measurement time series with a negative exponential function and then dividing by predicted values to remove age-related # declines in growth while preserving environmentally-induced variability. Detrended measurements were averaged by calendar year to generate # a master chronology for each species. # # Final chronologies span the following years for each species: # Alaska plaice: 1987-2006 (n=29 individuals) # Northern rock sole: 1989-2006 (n=28 individuals) # Yellowfin sole: 1989-2006 (n=21 individuals) # # Measurement type: annual growth-increment width (in mm) # 1st detrending method: Negative exponential # Collection purpose: Ecology; effects of climate variability on flatfish growth # Samples are stored at the Alaska Fisheries Science Center, NMFS, NOAA Seattle, WA, 98115, USA # # COFECHA output: # Alaska plaice: series intercorrelation = 0.59; mean sensitivity = 0.24 # Northern rock sole: series intercorrelation = 0.61; mean sensitivity = 0.23 # Yellowfin sole: series intercorrelation = 0.66; mean sensitivity = 0.26 # #-------------------- # Publication # Authors: Mary Elizabeth Matta, Bryan A.

Within each species, otoliths were visually crossdated to ensure that the correct calendar year was assigned to each growth increment. Growth-increment widths were measured in each otolith, crossdating was statistically checked, and a single master chronology was generated for each species by averaging measurement time series after age-related growth declines had been removed. The 3 final chronologies spanned 18 to 20 yr and were significantly correlated with each other (p < 0.001), indicating a high level of growth synchrony among species. Final chronologies were compared to annual and monthly climate variables including water temperature, ice cover, the Pacific Decadal Oscillation, and the El Nino Southern Oscillation. Of the climate indices examined, chronologies were most strongly related to summertime eastern Bering Sea bottom temperatures, with R2 values of 0.81, 0.61, and 0.34 for the yellowfin sole, Alaska plaice, and northern rock sole chronologies, respectively. Chronologies were significantly (p < 0.01) and positively related to monthly resolved records of sea surface temperature, though the seasons of the year exhibiting the strongest correlations varied among species. The present study suggests that flatfish growth is strongly influenced by the temperature of the eastern Bering Sea, underscoring the effect of climate on fisheries in a high-latitude ecosystem. #------------------ # Funding_Agency # Funding_Agency_Name: US National Oceanic and Atmospheric Administration (NOAA) # Grant: Fisheries and the Environment (FATE) program, Alaska #------------------ # Site_Information # Site_Name: Bering Sea # Location: Ocean>Pacific Ocean>North Pacific Ocean>Bering Sea # Country: # Northernmost_Latitude: 61.0 # Southernmost_Latitude: 56.0 # Easternmost_Longitude: -158.0 # Westernmost_Longitude: -175.0 # Elevation: 0 m #------------------ # Data_Collection # Collection_Name: Matta2010AKPotolith # Earliest_Year: 1979 # Most_Recent_Year: 2006 # Time_Unit: AD # Core_Length: m # Notes: #------------------ # Chronology: # AKP Master Chronology # # Year Sample_depth_AKP Final_AKP_chron # 1987 6 1.02 # 1988 6 1.188 # 1989 9 0.983 # 1990 11 1.097 # 1991 14 1.086 # 1992 19 0.967 # 1993 23 1.17 # 1994 24 0.882 # 1995 24 0.834 # 1996 27 1.008 # 1997 29 0.926 # 1998 29 1.021 # 1999 29 0.646 # 2000 29 0.896 # 2001 29 0.995 # 2002 29 1.052 # 2003 29 1.246 # 2004 29 1.1 # 2005 25 1.149 # 2006 8 0.925 # # # #---------------- # Variables # # Data variables follow that are preceded by "##" in columns one and two. # Data line variables format: Variables list, one per line, shortname-tab-longname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) # ##age_AD age, , , year AD, , , , ,N ##growthR106_105 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_105, ,N ##growthR106_106 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_106, ,N ##growthR106_107 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_107, ,N ##growthR106_109 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_109, ,N ##growthR106_110 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_110, ,N ##growthR106_111 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_111, ,N ##growthR106_116 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_116, ,N ##growthR106_178 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_178, ,N ##growthR106_184 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_184, ,N ##growthR106_186 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_186, ,N ##growthR106_188 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_188, ,N ##growthR106_192 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_192, ,N ##growthR106_194 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_194, ,N ##growthR106_198 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_198, ,N ##growthR106_199 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_199, ,N ##growthR106_200 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_200, ,N ##growthR106_234 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_234, ,N ##growthR106_236 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_236, ,N ##growthR106_237 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_237, ,N ##growthR106_238 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_238, ,N ##growthR106_241 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_241, ,N ##growthR106_248 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_248, ,N ##growthR106_250 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_250, ,N ##growthR106_251 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_251, ,N ##growthR106_252 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_252, ,N ##growthR106_289 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_289, ,N ##growthR106_302 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_302, ,N ##growthR106_309 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_309, ,N ##growthR106_332 Growth increment, Alaska Plaice otolith, , mm, , , sample R106_332, ,N # #---------------- # Data: # Data lines follow (have no #) # Data line format -
