본 독도 연안 해역에서 2019년 계절적 수환경 특성과 식물플랑크톤 군집구조 변화 특성을 파악하고, 2018년과 2019년 특성을 비교하고자 두 연도의 4계절 수층별 조사가 수행되었다. 2019년에는 총 4문 69종의 식물플랑크톤이 관찰되었고, 평균 식물플랑크톤 개체수는 1.90×10⁴ cells L-1로 매우 낮게 나타났다. 동계에는 평균 3.19×10⁴ cells L-1로 대부분 미동정 편모류가 우점하였고, 춘계에는 3.12×10⁴ cells L-1로 역시 편모류가 약 50%를 차지하였으며, P. obtusidens를 포함한 다양한 와편모조류가 출현한 특징이 있었다. 하계 개체수는 0.46×10⁴ cells L-1로 매우 낮은 개체수와 종이 나타났고, 추계에는 평균 개체수가 0.89×10⁴ cells L-1로 낮았으며, 여러 종의 Chaetoceros와 함께 Bacteriastrum spp., Guinardia striata, Psuedo-nitzschia spp. 과 같은 규조류가 다양하게 나타났다. 또한, 2018년 추계와 동일하게 열대 지표종인 Ornithocercus sp.와 Amphisolenia sp.가 관찰되었다. 2019년에는 대마난류와 남해 연안의 영향을 받은 종이 출현하였지만, 전반적으로 매우 낮은 개체수를 보이며 편모조류가 우점한 특징이 있었다. 식물플랑크톤 다양성은 2018년 하계와 2019년 동계에 높게 나타났고, 군집분석에서도 계절에 상관없이 크게 4개 그룹으로 구분되었다. 2018년과 2019년 수환경은 특이적으로 춘계에 성층이 약하게 형성되었고, 2018년 추계에는 하계와 동일하게 수괴가 안정되어 식물플랑크톤이 대증식한 것으로 사료된다. 식물플랑크톤 군집 및 개체수는 하계를 제외하고 계절별 우점 종의 차이를 보였으며, 이 차이는 추계에 가장 뚜렷하였다. 따라서 독도 연안 해역은 일반적인 동해의 특성과는 다르게, 외해역임에도 불구하고 얕은 지형과 다양한 해류, 섬효과 등과 같은 복합적인 영향으로 연도별 계절별 특성이 다르게 나타날 수 있다는 것을 시사한다.
