Abstract

The aims of the research are to determine correlation between chlorophyll a distribution and oceanographyparameter at North Papua Waters dan to identify oceanography parameter which have strong correlation onchlorophyll a distribution especially on East Monsoon. The purpose of the research provide an information aboutthe pattern of chlorophyll a distribution and key oceanography paramater which most affected on chlorophyll aconcentration at the research site. Temperature and salinity were measured using CTD (Conductivity TemperatureDepth) Guildline-6000. Waters ample for measuring chemical paramater was done using Super Rosette Samplerthat have Niskin Bottle that submerge with the CTD. The result showed oceanography parameter affectedsignificantly on chlorophyll a concentration based on depth, chemical parameter. This effect was higher than othereffects in particular on surface water till 200 meter depth. Keywords: oceanography parameters, chlorophyll a distribution, East Moonsoon and North Papua Waters

Abstract

The availability of fish in the fishing area is influenced by oceanography condition. In Makassar coastal waters, potential area of small pelagic fish is the main information for the fisherman. Purpose of this research is to provide information of oceanographic characteristics which connected with fishing potential area on east season. This research was conducted during May-December 2012, using field and secondary data. Potential area determination was analyzed by using polynomial model. Distribution of oceanographic factors was analyzed by SMS and surfer. Makassar has continent as well as island areas (12 islands). Oceanographic conditions indicate tidal current velocity of 0.08 m/s and ebb currents from 0.05 to 0.30 m/s. Sea surface temperatures in the spring waters east of Makassar were in the range of 26 -31oC. The concentration of chlorophyll-a occurred between 0.0 and 1.0 mg/m3, oceanographic conditions in July and August 2012 are relatively similar. Potential zone for small pelagic fish species in June, July, and August are in the waters around the islands - northern part of the island of Makassar and from the island to Lanyukkang Lumu-Lumu island.   
The researh for study relationship between phytoplankton abundance and environment parameters and determining contribuion each environment parameters on phytoplankton abundance discrimination had been conducted in 2005 in bagan rambo fishing ground at coastal water Barru Regency, Makassar Strait.  Environment parameters and phytoplankton abundance data collection were conducted on May (6 stations), June, July, September, October and November (9 stations).  Spatio-temporal distribution of envir Hatta, Muh.; Kaswadji, Richardus F; Purba, Mulia; Monintja, Daniel R.

Abstract

The researh for study relationship between phytoplankton abundance and environment parameters and determining contribuion each environment parameters on phytoplankton abundance discrimination had been conducted in 2005 in bagan rambo fishing ground at coastal water Barru Regency, Makassar Strait.  Environment parameters and phytoplankton abundance data collection were conducted on May (6 stations), June, July, September, October and November (9 stations).  Spatio-temporal distribution of environment parameters probably ralate to fresh water loading to stations inshore.  Phytoplankton abundance found in this research ranged from 431 to 5438 cels/liter.  Phytoplankton population dominated by diatom i.e: Bacteriatrum, Biddulphia, Chaetoceros, Coscinodiscus, Ditylum, Eucampia, Melosira, Navicula, Nitzschia, Rhizosolenia, Skeletonema, Thalassionema, Thalassiosira, dan Thalassiothrix.  Regression analysis result show significantly positive linear correlation between phytoplankton abundance with temperature and phosphate concentration, but low correlation coefficient R = 0,4366 (R2 = 0,1906).  Discriminant analysis result show that high average of phytoplankton abundance occured when high temperature and nitrat concentration, and moderate salinity, pH and phosphate concentration.  Phosphate concentration have higher contribution on discriminating phytoplankton abundance.  The contribution of nitrate and silicat concentration and pH are low.   Key words: phytoplankton, phytoplankton abundance, diatom, discriminant analysis, environment parameters
