Description:

Abstract:

This dataset contains the growth index from annual growth bands in the shells of two bivalve clam species (Astarte borealis and Liocyma fluctuosa) captured in the Chukchi Sea, Alaska. The growth index is based on a measurement of the annual growth increment width that has been detrended for age-related differences in growth.

Purpose:

Annual growth increments in bivalve shells were used to develop long-term baseline records of benthic productivity and gain retrospective insight about benthic community response to long-term reductions in sea ice in the eastern Chukchi Sea, Alaska.

Liocyma fluctuosum and Liocyma fluctuosa are both attributed to Gould (1841), although this reference only includes the fluctuosa spelling (Venus fluctuo'sa at the time, page 87) such that it appears slight variations in spelling for the same species exist. The Integrated Taxonomic Information System includes only one Liocyma species, Liocyma fluctuosum (Gould, 1841). We use Liocyma fluctuosa in this data release because it has been the dominant spelling in the literature for many decades. Gould, A.A. 1841.

Attribute_Accuracy_Report:

Growth-increment widths were measured continuously along the axis of maximum growth and perpendicular to growth-increment boundaries on digital images using the caliper tool in Image Pro Premier (version 10.0.6). Accuracy of +/-1 micron was estimated based on repeated measurements of the scale bar used for calibration. Image resolution resulted in 0.905 pixels per 1 micron

Methodology:

Methodology_Type: Field
Methodology_Description:

Live A. borealis and L. fluctuosa shell valves were collected from locations along the northwest Alaskan coastline (70°26'N, 162°45'W and 71°41'N, 157°36'W for A. borealis and L. fluctuosa respectively), at depths ranging from 20 to 40 m, between 2012 and 2016 by means of beam trawl and clam dredge.

Methodology:

Methodology_Type: Lab
Methodology_Description:

One shell valve of each selected sample was fully embedded in EpoxyCureTM 2 epoxy resin and sectioned, using a Buehler Isomet 1000 precision saw and diamond wafering blade along the axis of maximum growth from the umbone to the margin. One half of each embedded sectioned sample was then polished using progressively finer grits (from grade 400-2000) carborundum paper followed by 3um monocrystalline diamond solution on an Ecomet 30 auto-polisher. The polished shell surface was etched in 0.1M HCl for 45 seconds and an acetate peel replica constructed using conventional techniques. Digital photomosaics were then generated by digitally photographing the hinge area of each acetate peel under 10x-100x magnification using a Leica M205C microscope coupled with LASX software and Adobe Photoshop CC. Growth-increment widths were then measured continuously along the axis of maximum growth and perpendicular to growth-increment boundaries using Image Pro Premier (version 10.0.6)on the digital photomosaics. A complete set of growth-increment widths cannot always be measured from each individual because clarity of increments can vary within an individual. The most recent growth-increments must be clear enough to count for assignment of calendar years, but are not always clear enough for measurements because the boundaries may be fuzzy and indistinct. It is not necessary to count or measure the oldest-growth increments if they are unclear.

Process_Step:

Process_Description:

To arrive at the growth index, growth-increment widths from each individual shell were detrended using flexible splines (7-21 years) to isolate high-frequency variability and remove age-related differences in annual growth (i.e., younger individual tend to grow faster than older individuals). The result is a unitless index based on the width of an annual growth increment that has been detrended to remove age-related differences in growth rates for each individual shell. A value of 1.0 indicates that growth was exactly as expected for the age when the increment was formed (i.e., neither good nor poor growth). Values below 1.0 indicate slower (i.e., poor) than expected growth at age. Values greater than 1.0 indicate faster (i.e., good) than expected growth at age.
