Comparison of two methods for sampling invertebrates on submerged vertical walls with diving

Comparisons of methods for sampling submerged vertical areas and bottoms while scuba diving were made in Silfra, a freshwater fissure in Þingvellir National Park, southwest Iceland. A modified Surber sampler and a constructed manual suction pump sampling system were used to take 20 samples at two depths at a chosen transect in the fissure. After counting and classifying the zoobenthos encountered in the samples, statistical analysis was conducted. My results show that the manual suction pump system collected a greater number of both individuals and taxa at the two depths in question. It´s use also proved more practical and reliable for the various conditions encountered in the fissure.
