The Birge‐Ekman box corer has been modified for use by SCUBA divers or deep submergence research vessels, thus allowing control in the precision of sampling. Data suggest that the modified box corer exhibits greater accuracy and precision in estimating the abundance of species and individuals than conventional surface ship samplers or smaller corers used widely for in situ investigations.
