SEAMAP] Observation error variance for SEAMAP index, 1990-2008 [[alpha].
The NEFSC and SEAMAP indices were chosen because the corresponding surveys showed wide geographic coverage, temporal coverage, or both; have been conducted consistently; and have provided evidence of regular encounters with Atlantic Croaker of different age groups (ASMFC; (1) Appendix 1).

For example, only 37 grouper larvae were collected in gulf-wide SEAMAP ichthyoplankton surveys between 1982 and 1999 (>7000 samples) (Lyczkowski-Shultz et al.
