As reported on Afloat.ie in October, the month-long volunteer survey took in use of land and shore, water quality, pollution levels and marine wildlife and plantlife.
More than 18,000 drinks containers - mostly plastic bottles - were found by volunteers on the 3% of Irish coastline sampled for the survey.
And despite a 50% fall over 14 years, sanitary waste such as condoms and dirty nappies were still a problem on beaches.
While suggesting a broadening of the plastic bag levy, Dubsky also called for a 'deposit on return' scheme for drinks containers to reduce letter and encourage recycling.
The survey also reported more positive news, with nitrate levels in outflow waters below detection in half the surveyed areas for the first time since 1993.
