    Geochemistry of the marine sediments
    (Hokkaido University, 1999) Kamaruzzaman, Hj. Yunus
    A goal of this study is to obtain a clear and systematic description of the sediment which may give a clue of the accumulation history and the paleoproductivity in the ocean. In this study, I have obtained a sediment cores from the northern North Pacific Ocean (station 3) and the Bering Sea (station 4) in order to elucidate the record of the past and present. The sediment cores, which differed in redox conditions, have been studied by measuring several chemical elements (Ba, opal, U, Cd, Mn, Ti and Al), radionuclides (- ^-Th, 230rh) as well as the contents of carbonate and organic carbon. Both cores consists of diatomaceous ooze, with a core at station 4 containing a fairly large amount of biogenic opal although it is dominated with fine-grained terrigenous material.

    Kajian beberapa aspek parameter fiziko-kimia di dalam sistem muara sungai Chukai-Kemaman, Terengganu
    (Fakulti Pengajian Maritim dan Sains Marin, 1994-11) Kamaruzzaman, Hj. Yunus
    Kajian menyeluruh aspek fiziko-kimia telah dijalankan di Sungai Chukai dan Sungai Kemaman bagi mengetahui kesan pembangunan dan status pencemaran di kedua-dua sungai tersebut. Beberapa aspek kajian telah dijalankan di Sungai Chukai dan Sungai Kemaman termasuk saliniti, suhu dan arus, sedimentologi, kandungan karbon dan logam. Sebanyak empat penyampelan telah dilakukan iaitu dua kali pada musim luar hujan (bulan Julai/92 dan Mei/93) dan dua kali pada musim hujan (September/92 dan Februari/93). Kajian dijalankan ke atas sebanyak 25 stesen iaitu 11 stesen di Sungai Chukai dan 14 stesen di Sungai Kemaman.
