The chronologies are compared to local and remote environmental drivers suspected to influence the biology of the system, including air and seawater temperature, precipitation and freshwater discharge. The Adriatic-Ionian Bimodal Oscillating System (BiOS), a key oceanographic feature quantified by satellite-derived absolute dynamic topography, is also compared to the chronologies. The chronologies at the two southern sites are more strongly influenced by local river discharge, while the two northern chronologies are more strongly influenced by BiOS. These results highlight the broadscale importance of BiOS to the Adriatic system as well as the heterogeneity of nearshore environmental and drivers of growth. These G. pilosa chronologies provide unique multidecadal, continuous, biological time series to better understand the ecology and fine-scale variability of the Adriatic with potential for other shallow, semi-enclosed seas. #------------------ # Publication # Authors: M.

Here, we document that well-replicated and exactly dated chronologies can also be developed to capture oceanographic processes in temperate and semi-enclosed seas, such as the Mediterranean. A chronology is constructed for Glycymeris pilosa from a shallow embayment of the northern Adriatic and extends from 1979 to 2016. The chronology significantly (p < 0.05) and positively correlates to winter sea surface temperatures, but negatively correlates to summer temperatures, which suggests that extreme winter lows and extreme summer highs may be limiting to growth. However, the strongest and most consistent relationships are negative correlations with an index of the Adriatic-Ionian Bimodal Oscillating System (BiOS) for which positive values indicate the inflow of the ultraoligotrophic Eastern Mediterranean waters to the Adriatic. In contrast, the substantial freshwater flows that discharge into the Adriatic do not correlate to the bivalve chronology, emphasizing the importance of remote oceanographic processes to growth at this highly coastal site. Overall, this study underscores the potential of bivalve chronologies to capture biologically relevant, local- to regional-scale patterns of ocean circulation in mid-latitude, temperate systems. #------------------ # Publication # Authors: Melita Peharda, Bryan A.

Maximal longevity of analyzed shells was 69 years. Growth increments in acetate peels of the hinge region had clear boundaries, and there was a strongly synchronous signal in growth-increment width among individuals. The final, replicated chronology spanned 1969 to 2013. Shell growth negatively correlated with local summer sea temperatures and positively with November precipitation. High correlation between shell growth and circulation patterns in the northern Ionian was also observed, with slower growth occurring during cyclonic regimes. Given its broad distribution in the region and the ability to crossdate, generate annually-resolved chronologies, and of a length that substantially overlaps with observational records, G. pilosa has considerable potential to test hypotheses relating to environmental variability and biological response in the Mediterranean. #------------------ # Funding_Agency # Funding_Agency_Name: Croatian Science Foundation # Grant: IP-2014-09-5747 #------------------ # Site_Information # Site_Name: Istra # Location: Ocean>Atlantic Ocean>North Atlantic Ocean>Mediterranean Sea # Country: Croatia # Northernmost_Latitude: 44.9854 # Southernmost_Latitude: 44.9854 # Easternmost_Longitude: 13.73867 # Westernmost_Longitude: 13.73867 # Elevation: #------------------ # Data_Collection # Collection_Name: Peharda2019Istra # Earliest_Year: 1978 # Most_Recent_Year: 2013 # Time_Unit: CE # Core_Length: # Notes: #------------------ # Chronology_Information # Chronology: # #---------------- # Variables # # Data variables follow are preceded by "##" in columns one and two. # Data line variables format: one per line, shortname-tab-variable components (what, material, error, units, seasonality, data type,detail, method, C or N for Character or Numeric data, free text) # ## age_CE age, , , year Common Era, ,paleoceanography , ,,N, ## sgi growth rate,bivalve, ,dimensionless, ,paleoceanography,composited,,N,standardized growth index; annually resolved Glycymeris pilosa growth increment width chronology # #---------------- # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing_Values: NaN # age_CE sgi 1978 1.125 1979 1.114 1980 1.004 1981 1.035 1982 0.841 1983 0.995 1984 1.176 1985 0.959 1986 1.062 1987 0.933 1988 1.077 1989 1.078 1990 1.308 1991 1.293 1992 1.003 1993 1.005 1994 1.052 1995 1.127 1996 1.046 1997 1.132 1998 0.636 1999 0.889 2000 0.893 2001 0.889 2002 0.823 2003 0.938 2004 0.794 2005 0.998 2006 0.986 2007 0.995 2008 1.018 2009 0.962 2010 1.025 2011 0.956 2012 0.916 2013 1.299 2014 1.065 2015 1.06 2016 1.176
