STRATIFIKASI DAN STRUKTUR MASSA AIR LAUT BANDA SAAT MUSIM TIMUR

چکیده

Laut Banda termasuk jalur Arlindo bagian timur, sebagai reservoir sementara massa air, dan merupakan wilayah Upwelling yang bervariasi secara musiman tergantung dari arah musim. Penelitian ini Ekspedisi Jala Citra 2-2022 bertujuan untuk mengkaji stratifikasi air di Banda. Proses sampling menggunakan CTD Rosette pada 6 Stasiun pengamatan meliputi data suhu, salinitas densitas. Analisa melihat pelapisan sedangkan analisa lapisan Gumbar (Core Layers), analisis isopiknal diagram TS struktur air. Hasil penelitian menunjukan variasi densitas cukup besar permukaan. Pada termoklin ditemukan dengan maksimum (Smax) mencapai 34,79 Psu, kisaran suhu 17,09-230C 23,99-25,45 Kg/m3 berada kedalaman 106-187 m. bawah 34,81 8,67-12,790C 26,41-27,01 230-402 Salinitas minimum (Smin) 26,11-26,56 34,36 Psu 234-324 m 10,60-12,580C. Lapisan dalam 33,48-34,74 674-1000 4,59-6,940C serta >27 Kg/m3. Massa memiliki Smax diyakini adalah NPSW. karakter SPLTW Smin NPIW. lebih AAIW. The Sea, a part of the Eastern line which is also an area upwelling that varies seasonally depending on season's direction, plays important role as temporary water masses. This research Expedition aims to study stratification masses in Sea. process uses at observation stations includes temperature, salinity and density data. Water mass analysis used see layering mass, while core layers analysis, isopicnal for structure analysis. results showed variations are quite large surface layer. In thermocline layer, with maximum found reached temperature range depth At bottom thermocline, reaching deep more than 27 layer has believed be NPSW mass. lower character deeper AAIW
