The present report provides information on 20 pontoniine shrimp taxa from the island of Socotra, collected by Dr Michael Apel, including two new species, of the genera Dactylonia Fransen and Periclimenoides Bruce. Thirteen species are reported from Yemen for the first time, 8 are newly recorded from the north western Indian Ocean. The record of Periclimenoides is the first occurrence of this genus in the western Indian Ocean. The number of pontoniine shrimps known from the north west Indian Ocean is now increased from 32 to 44 taxa.

The benthic ctenophore Vallicula multiformis Rankin, 1956 is recorded for the first time in the Arabian Sea, from the Gulf of Kutch, west coast of India in March 2013. This occurrence represents a remarkable extension of its geographic distribution that until now included only known the Pacific and Atlantic oceans.

Modern goniasterids are the most numerous of living asteroids in terms of described genera and species and they have important ecological roles from shallow to deep-water marine habitats. Recent MNHN expeditions and historical collections in the USNM have resulted in the discovery of 18 new species, three new genera and multiple new occurrence records from the western Indian Ocean region including Madagascar, Glorioso and Mayotte islands, Walters Shoal, South Africa, and Somalia. This report provides the first significant contribution to knowledge of deep-sea Asteroidea from the Indian Ocean since the late 20th Century. Several deep-sea species, previously known from the North Pacific are now reported from the western Indian Ocean. Gut contents from Stellaster and Ogmaster indicate deposit feeding. Feeding modes of this and other deep-sea species are discussed. Comments are made on fossil members of included taxa. A checklist of Indian Ocean Goniasteridae is also included.

The article deals with the report of 5 suctorians viz. Lecanophryella satyanandani (Santhakumari, 1986), Paracineta karunakarani Santhakumari, 1986, Ephelota gemmipara (Hertwig, 1876), Acineta foetida Maupas, 1881 and Pelagacineta sp. on marine pelagic ostracods Cypridina dentata (Müller, 1906) from new localities of the Arabian Sea. Diagnostic characters of Paracineta karunakarani are emended. Ephelota gemmipara (Hertwig, 1876) and Acineta foetida Maupas, 1881 are reported here for the first time on planktonic marine ostracods. Pelagacineta sp. is reported for the first time as epibiont on ostracods and from the Indian Ocean.

Sergestes edwardsii Kröyer, 1855 species group is composed of 9 species: S. semissis  (Burkenroad, 1940);  S. gibbilobatus (Judkins, 1978);  S. orientalis (Hansen, 1919);  S. geminus (Judkins, 1978);  S. tantillus (Burkenroad, 1940); S. consobrinus (Milne, 1968) California Current Form;  S. consobrinus (Milne, 1968) Central Form; S. edwardsii (Kröyer, 1855); S. brevispinatus (Judkins,1978).  The bathypelagic  shrimps  belonging  to  the  genus Sergestes  are  being studied from the  IIOE  material  for  its  taxonomy  and distribution.  Two species, S. brevispinatus (Judkins,1978) and  S. edwardsii (Kröyer, 1855), have been collected by the research vessels  ANTON BRUNN, ARGO, DIAMANTINA, METEOR, OSHORO MARU and VARUNA in the Indian Ocean for the first time.  Sergestes edwardsii is broadly distributed throughout the tropical Atlantic; it occurs from the New Land Plaza, Canada, to the wide of the Great Power of the North; throughout the Caribbean and Gulf of Mexico. Records at high northern latitudes in the Western Atlantic are probably due to transport by the Gulf Stream (Judkins, 1978). In Brazil it occurs in Para, in the Archipelago of Are Peter and Sao Paulo, Great River of North Fermando De Noronho  (D’Incao, F., 1995, 1998). Specimens of the present material are housed in the Marine Reference Collection and Resource Centre (MRC&RC), University of Karachi.

Oxygen maxima, in relation to σt salinity maxima and minima, and other hydrological structural features, have been examined along three meridional sections of the Indian Ocean. These relations have provided a background for the interpretation of the water mass sources of oxygen maxima of the whole Indian Ocean. After grouping these oxygen maxima according to density, their salinities have been used to identify mixing circuits in which the following waters are involved: from the south (1) South Indian Central, (2) Subtropical oxygen maximum, (3) Antarctic Intermediate; from the east (4) Equatorial Frontal water; and from the north (5) Persian Gulf, and (6) Red Sea. The principal routes whereby oxygen-rich mixtures of these waters enter the Arabian Sea, during the south-west monsoon, have been determined. The directions of flow along several of these routes agreed with measured directions of current flow. Where these currents disagreed the measured current was generally very weak.

Anthropogenic iron deposition alters the ecosystem and carbon balance of the Indian Ocean over a centennial timescale

The Impact

<p>Phytoplankton growth in the Indian Ocean is generally limited by macronutrients (nitrogen: N and phosphorus: P) in the north and by micronutrient (iron: Fe) in the south. Increasing anthropogenic atmospheric deposition of N and dissolved Fe (dFe) into the ocean can thus lead to significant responses from marine ecosystems in this ocean basin. Previous modeling studies investigated the impacts of anthropogenic nutrient deposition on the ocean, but their results are uncertain due to incomplete representations of Fe cycling. We use a state-of-the-art ocean ecosystem and Fe cycling model to evaluate the transient responses of ocean productivity and carbon uptake in the Indian Ocean, focusing on the centennial time scale. The model incorporates all major external sources and represents a complicated internal cycling process of Fe, thus showing significant improvements in reproducing observations. Sensitivity simulations show that after a century of anthropogenic deposition, increased dFe stimulates diatoms productivity in the southern Indian Ocean poleward of 50⁰S and the southeastern tropics. Diatoms production weakens in the south of the Arabian Sea due to the P limitation, and diatoms are outcompeted there by coccolithophores and picoplankton, which have a lower P demand. These changes in diatoms and coccolithophores productions alter the balance between the organic and carbonate pumps in the Indian Ocean, increasing the carbon uptake in the south of 50⁰S and the southeastern tropics while decreasing it in the Arabian Sea. Our results reveal the important role of ecosystem dynamics in controlling the sensitivity of carbon fluxes in the Indian Ocean under the impact of anthropogenic nutrient deposition over a centennial timescale.</p>

Malayalam is the language of the south-west of the Madras Presidency. It is the third most important language of the Presidency, the first and the second being Tamil and Telugu respectively. It is spoken in Malabar, Cochin, and Travancore. Out of a total of 5,932,207 inhabitants of these parts, 5,409,350 persons are those who speak Malayalam. These countries, taken as a whole, are bounded on the north, by South Canara, on the east by the far-famed Malaya range of mountains, on the south by the Indian Ocean, and on the west by the Arabian Sea.
