Strict warning: Declaration of iform_big_sea_survey::getEntity() should be compatible with 
iform_dynamic_sample_occurrence::getEntity(&$args, $auth) in require_once() (line 37 of
iform/client_helpers/prebuilt_forms/big_sea_survey.php).

Strict warning: Declaration of iform_tree_sample_occurrence::getEntity() should be compatible
with iform_dynamic_sample_occurrence::getEntity(&$args, $auth) in 
form_helper::prebuilt_form_picker() (line 68 of iform/client_helpers/form_helper.php).
