Abstrak : Tujuan penelitian adalah untuk mngetahui tingkat pencemaran di Teluk Jakarta. Dari aspek oseanografi ialah salah satu untuk mendapatkan informasi yang lengkap mengenai pola distribusi arus telah dikerjakan pada bulan Juni, September 2003 dan Mei , Nopember 2004 masing-masing sebanyak di 36 stasiun. Pengkukuran parameter arus dengan menggunakan CM2X direct reading current meter. Pola arus bulan Juni dan September 2003 secara umum arus permukaan ke arah barat daya sampai barat laut dan arus di dekat dasar menuju ke arah pantai, kecuali dari sungai arahnya menuju ke arah laut lepas. Pola arus bulan Mei 2004 secara umum di bagian permukaan datang dari arah timur laut ke arah barat laut. Pola arus di dekat dasar bahwa arus dari sungai-sungai sebelah barat teluk ke arah barat laut dan di sebelah timur teluk ke arah barat laut serta pola arus di bagian tengan arah arus ke arah pantai dan berbelok ke arah timur laut dan barat laut menyusur pantai.

Kata kunci : Arus, dan Teluk Jakarta.

Abstract : Objective of research is to know pollution level in Jakarta Bay. From physical oceanography aspect is one of to get information regarding current distribution pattern were carried out in June, September 2003 and May 2004 in 36 stations respectively. Measuring of current speed and direction is by using CM2X direct reading current meter. Current pattern on June and September 2003 has been generally that sea surface current toward north-west until south-west and current at near bottom has to coastal direction, except from rivers that its direction has to offshore direction. Current patrren on May 2004 has generally that sea surface current was come from northeast direction to southwest. Current pattern at near bottom that current from rivers of westside bay has northwestwards and in eastside bay has northwestwards and also current pattern in central part of bay that current pattern to onshore direction and turn to northeastwards and northwest is along the shore.

Keywords : Current, river, and Jakarta Bay.
