Struktur Komunitas Fitoplankton di Perairan Pantai Megaproyek PLTU Batang, Jawa Tengah
Adanya aktivitas pembangunan Megaproyek PLTU Batang diduga akan menurunkan kualitas lingkungan perairan khususnya di sekitar Megaproyek PLTU Batang. Salah satu organisme penting bagi ekosistem perairan adalah fitoplankton yang memaninkan perairan dalam produktivitas primer. Fitoplankton adalah mikro organisme autotrof yang dapat dijadikan sebagai indikator kualitas perairan.

期刊介绍:
The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
