Abstract This study focused on diagnosing the relative and independent role of El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) on austral cool seasonal rainfall by stratifying the cool seasonal rainfall into winter (June–August) and spring (September–November). Partial regression and classification analysis was used to investigate the effect of the climate modes on rainfall in the state of Victoria in southeast Australia. Partial regression analyses revealed that when the influence of IOD is removed from ENSO, sea surface temperature (SST) anomalies in the Pacific Ocean have no significant effect on spring rainfall across Victoria and affect winter rainfall mildly in west Victoria. By removing the inter-correlations between ENSO and IOD, SST anomalies in the Indian Ocean and SLP anomalies in the Pacific Ocean showed weak relationships with Victoria's spring and winter rainfall. Classification analysis demonstrated the effects of phases of ENSO and IOD on Victoria's seasonal rainfall; the dry phases of the climate modes have more effect on spring rainfall compared to the wet phases and both show no significant effect on winter rainfalls. It is recommended that for water availability forecasting in Victoria, water managers should focus on the effect of climate modes on spring rainfalls, particularly during the dry phases of ENSO and IOD.

The study assesses the covariability of Sea Surface Temperature (SST) and March to May (MAM) rainfall variability on East Africa (EA) from 1981 to 2018. Singular Value Decomposition (SVD) analysis reveals the significant influence of SST anomalies on MAM rainfall, with covariability of 91%, 88.61%, and 82.9% for Indian, Atlantic, and the Pacific Ocean, respectively. The Indian Ocean explains the variability of rainfall to the large extent followed by the Atlantic Ocean and the Pacific Ocean. The rainfall patterns over the EA correspond to SST variability over the western, central, and Eastern Indian Ocean. Likewise, the variability of SST anomalies was observed over the central, south, and North of the Atlantic Ocean while the Pacific Ocean captured the El Nino Modoki (ENSO) like pattern in the SVD1 (SVD2). The heterogeneous correlation of Indian SST anomalies and rainfall over EA of the first (second) principal component (PC) shows a positive correlation over much of the domain (central region). The SST anomalies over the Pacific Ocean show higher correlation values with the rainfall over much of the study domain except over the southwestern highland and southern region of Tanzania. Over the Atlantic Ocean, the correlation result shows the patterns of positive (negative) values over the northern (southern) part for PC1, while PC2 depicts negative correlation values over much of the Ocean. SST anomalies over the Indian (Atlantic) Ocean are highly correlated with MAM rainfall when SST leads by 1(7) month(s). The Pacific Ocean shows a weak (strong) correlation across all (zero) lead seasons.

Cubiceps baxteri McCulloch 1923 was described based on a single, imperfect (devoid of a tail) stranded specimen collected from a beach in Lord Howe Island, Tasman Sea. Though C. baxteri was reported as a widely distributed tropical species (Butler 1979), it was mainly a result of its incorrect identification (see Agafonova 1994; Stewart and Last 2015). The distribution of C. baxteri is reported to be restricted to the Pacific Ocean, from Japan and eastwards to Baja California (Mexico), southwards to the Hawaiian Islands, New South Wales (Australia), and Lord Howe Island (Tasman Sea) to the Southern parts of Chile (Eschmeyer et al. 2017; Mundy 2005; Agafonova 1994).

Despite indications that the Pacific Ocean is helping to take up the world's missing surface heat, it is not storing the heat; oceanographers now find the ocean has moved heat over to the Indian Ocean.

The Way

Nusantara adalah suatu wilayah kepulauan yang berada di antara dua benua, Asia dan Australia, sebagai benua yang berada dalam dua samudera raya yang di kenal sebagai samudera India dan samudera Pasifik. Kepulauan ini memotong ekuator dari 95 derajat sampai 141 derajat bujur timur. Penduduk pulau ini menarik perhatian berbagai masyarakat dari penjuru dunia, karena tanah subur dengan  limpahan rempah-rempah dan corak masyarakat yang akomodatif dengankecenderunganfriendly dengan kehadiran tamu. Hal ini memicu para pedagang untuk berniaga dan sekaligus bersyiar atau berdakwah. Orang India yang beragama Hindu dan Buddha menjadi orang pertama yang berlabuh untuk berdagang dan sekaligus memperkenalkanagama yang di anut. Hal ini menjadikan identitas sangat bagus untuk diperbincangkan. Sebagai pendatang dantamu di Nusantara, orang-orang India membawa segala identitas termasuk budaya dan agama. Paper ini menjelaskan cara agama dari India hidup dan besar di tengah masyarakat.[The Nusantara is an archipelago located between two continents, Asia and Australia, as a continent located in two major oceans known as the Indian Ocean and the Pacific Ocean. These islands intersect the equator from 95 degrees to 141 degrees east longitude. The inhabitants of the island attract the attention of various people from all over the world because the land is fertile with an abundance of spices and an accommodating community style with a friendly inclination to the presence of guests. It triggered the traders to trade and simultaneously spread or preach. Indians who were Hindus and Buddhists were the first to anchor to trade and at the same time introduce the religion adherence embraced. It makes identity important to talk about. As guests and guests in the archipelago, Indians carry all identities, including culture and religion. This paper explains the way religions from India live and grow in society.]

In Situ Observations

A female ovigerous specimen of the rare deep-living hyperiid Megalanceoloides remipes (Barnard, 1932) was collected with a remotely operated submersible (ROV) at a depth of 2,094 m in the Farallon Basin, Gulf of California. The specimen was found to be symbiotically associated with the siphonophore Apolemia sp. Eschscholtz, 1829. Hitherto, this species was known only from two other specimens, one from the South Atlantic and another from the Indian Ocean; the present record is the first from the Pacific Ocean. Previous descriptions lacked morphological details of different appendages; these data are provided here. In addition, we present the first data on its symbiotic association from in situ observations. The colors of the hyperiid and of some parts of the Apolemid were very similar, thus supporting the notion that some hyperiids tend to mimic the color of its host.
