Abstract

Background

The growing interest in mineral resources of the deep sea, such as seafloor massive sulphide deposits, has led to an increasing number of exploration licences issued by the International Seabed Authority. In the Indian Ocean, four licence areas exist, resulting in an increasing number of new hydrothermal vent fields and the discovery of new species. Most studies focus on active venting areas including their ecology, but the non-vent megafauna of the Central Indian Ridge and South East Indian Ridge remains poorly known.

In the framework of the Indian Ocean Exploration project in the German license area for seafloor massive sulphides, baseline imagery and sampling surveys were conducted yearly during research expeditions from 2013 to 2018, using video sledges and Remotely Operated Vehicles.

New information

This is the first report of an imagery collection of megafauna from the southern Central Indian- and South East Indian Ridge, reporting the taxonomic richness and their distribution. A total of 218 taxa were recorded and identified, based on imagery, with additional morphological and molecular confirmed identifications of 20 taxa from 89 sampled specimens. The compiled fauna catalogue is a synthesis of megafauna occurrences aiming at a consistent morphological identification of taxa and showing their regional distribution. The imagery data were collected during multiple research cruises in different exploration clusters of the German licence area, located 500 km north of the Rodriguez Triple Junction along the Central Indian Ridge and 500 km southeast of it along the Southeast Indian Ridge.

Introduction

The Central Indian Ridge (CIR) and South East Indian Ridge (SEIR) are part of a global oceanic ridge system with high magmatic activity, which creates new seafloor, volcanoes and hydrothermal vent fields (Kelley 2001, Wang et al. 2012). High-temperature hydrothermal activity is often focused along topographically shallow portions of a single ridge segment, where a large magma reservoir causes crustal buoyancy (Ballard et al. 1981, Francheteau and Ballard 1983, Herzig and Hannington 1995). The hydrothermal activity accumulates polymetallic sulphides on the seafloor that may form seafloor massive sulphide (SMS) deposits with high content of iron, copper, zinc and rare earth metals in economically valuable amounts (Van Dover 2011, Miller et al. 2018, Van Dover 2019). The highly abundant and mostly symbiotic fauna that exist in hydrothermally active deposits in the Indian Ocean benefit from bacterial primary production and consist mainly of shrimp swarms, bivalve mussel beds and dense anemone fields (Hashimoto et al. 2001).

Along the spreading axes of the Indian Ocean, exploration licences for SMS deposits as potential mineral resources are issued by the International Seabed Authority (ISA; www.isa.org.jm). The ISA manages the areas beyond national jurisdiction (Levin et al. 2016) and regulates the human activities in the context of mineral resource exploration and exploitation that may take place in the near future (Ramirez-Llodra et al. 2011). This includes the protection of the marine environment from anthropogenic impacts, such as mineral extraction and mining technology testing (Rogers et al. 2012, Levin et al. 2016, Miller et al. 2018). To date, seven exploration licences for SMS deposits have been issued by the ISA; three on the Mid-Atlantic Ridge (MAR) and four in the Indian Ocean (www.isa.org.jm).

Possible future mining events at inactive hydrothermal vents will physically remove hard substrates and the local fauna, thereby flattening the vertical topography and permanently reducing habitat heterogeneity (Van Dover 2014, Levin et al. 2016, Van Dover et al. 2020). Since inactive vents may act as stepping stones for population recolonisation, removal of substrate during SMS mineral extraction may halt recolonisation (Van Dover 2014, Van Dover et al. 2020).

Such mining-related activities and disturbances will likely affect the hydrothermal vent fields and their surrounding areas, making taxonomic and ecological baseline studies essential for describing undisturbed environmental conditions and assessing potential mining impacts (Copley et al. 2016). Imagery-based studies are an accurate and cost-effective tool (Sen et al. 2014, Van Dover 2014), as they are able to detect environmental changes or serious harm (Van Dover 2019) to the ecosystem.

Deep-sea megafauna are important components of biodiversity and play significant roles in ecosystem functioning, as pointed out for megafauna occurring in nodule areas (Smith et al. 2008, Vanreusel et al. 2016). These ecosystem functions include utilisation rates of surface derived detritus, dietary composition or the locomotion mode. Megafauna are likely subject to drastic changes due to mining activities and are expected to recover slowly related with slow rates of growth and recruitment (Ramirez-Llodra et al. 2011, Amon et al. 2016, Gollner et al. 2017). Many megafauna taxa are considered as indicators of physical disturbance responding to disturbance events with changes in densities, dominating taxa or the community composition (Bluhm and Gebruk 1999, Amon et al. 2017).

Environmental research has been conducted in the framework of the German Indian Ocean Exploration (INDEX) project and includes biological benthic baseline studies in accordance with ISA environmental guidelines (www.isa.org.jm (ISBA/25/LTC/6/Rev.1); Ardron et al. 2011, Miller et al. 2018). The German licence area (GLA) in the Indian Ocean is located along the southern CIR and northern SEIR (Fig. 1). The INDEX project is conducted by the Federal Institute for Geoscience and Natural Resources (BGR, www.bgr.bund.de) and aims to find massive sulphide deposits in economically valuable amounts for potential exploitation. The GLA covers 100 exploration blocks, each 10 x 10 km in size, with a total area of 10,000 km2 of deep-sea floor. A vast number of photographs and video material has been collected during annual expeditions from 2013 to 2018 and has been used to create annual fauna catalogues of specific regions or clusters within the licence area.

This study combined the existing imagery of the taxa observed within the GLA to create a taxonomic expert-revised faunal catalogue with consistent identifications for the six years of exploration. The goal of the image analysis was to assess the species richness of benthic megafauna within the GLA, covering active and inactive hydrothermal vent fields and their surrounding non-vent areas, namely the abyssal deep-sea areas along the spreading axis of the southern CIR, the Rodriguez Triple Junction (RTJ) and the northern SEIR.

Materials and methods

INDEX expeditions and imagery acquisition

Six expeditions in consecutive years from 2013 to 2018 were used for this imagery study and covered a cumulative bottom track distance of 220,983 m. A total of 122,918 photographs and 367 hours 10 minutes of video imagery were collected. All photographs were reviewed and faunal occurrences annotated and extracted; video imagery was only used when additional imagery was necessary to clarify the imagery-based identification. The study area has a bathymetrical range of 2,280 – 3,770 m and spanned a geographical range from the MESO areas (after RV Meteor and RV Sonne; Muench et al. 1999) outside the German licence area on the southern CIR at 23°23'S, 69°14'E, to Cluster 12 on the northern SEIR at 27°42'S, 73°44'E (Fig. 1). The MESO area was studied during the pre-exploration period and later excluded before signing the exploration licence in 2015.

All imagery transects were conducted using three different video sledges and three Remotely Operated Vehicles (ROVs). The towed video platforms were the Multifunctional Tool (MFT) and the STROMER (STR), both belonging to the BGR and the video sledge (VS) of the Royal Netherlands Institute for Sea Research (NIOZ). The ROVs were the Kiel 6000 from the GEOMAR, the Remotely Operated Platform for Ocean Science (ROPOS) of the Canadian Scientific Submersible Facility (CSSF) and the ROV Victor 6000 of the IFREMER. Table 1 lists gear details and total photographs and video imagery collected. Table 2 lists specifications of the sampling gear, such as the camera equipment used and the imagery resolution.

Megafaunal imagery analysis

All taxa visible in photographs and video were annotated, cut out, and the individuals identified to the lowest taxonomic level possible. Photographic analysis was carried out using Adobe Photoshop Lightroom 5.7 (©2019 Adobe Systems Software Ireland Ltd.; www.adobe.com). Photographs were imported and automatically white-balanced and tone-corrected; year and station were added to the metadata for standardisation purposes and use in an imagery database.

Each photograph was magnified until identification was impossible due to pixelation and each section searched for both sessile and motile animals (Schoening et al. 2012). For each individual organism, a copy was created and the section containing the animal cut out. Folders were created in Lightroom in a taxonomic hierarchy following the classification in the World Register of Marine Species (WoRMS Editorial Board 2021). The morphotype or species and the abundance in the photographs were written into the metadata and resulted in up to 100 cut-outs from different photographs of individual taxa. The initial identification was based on taxonomic and imagery databases, photograph and video imagery galleries and scientific publications. In addition, selected images of all taxa were validated by the respective taxonomic experts of the team to check for consistency of the initial identification (Suppl. material 1).

The metadata of the processed photographs were exported and included taxon, abundance, expedition, year, station, GPS coordinates and technical information about the camera using the plug-in ListView (www.lightroomsolutions.com) for Adobe Photoshop Lightroom; the fauna catalogue shows selected images of each taxon.

The video imagery analysis was carried out with the video processing programme Magix Video deluxe 2014 Premium (©2003-2020 MAGIX Software GmbH; www.magix.com) primarily using video tracks from the ROVs; MFT video imagery was only processed in addition to photographs, if supporting the identification.

Both frame grabs from the video and short video films were exported and the frame grabs were used for the extension of the fauna catalogue. Short video films were cut out and added if the movement was characteristic for the animal and, therefore, helpful for identification (pers. comm. H. Singh Woods Hole Oceanographic Institute, Massachusetts, USA). The identification process was carried out in the same way as for the photographs. Detailed metadata information, such as sample locations, gear, depth, sampled specimens and camera information are listed in Suppl. material 1.

Sample collection

A total of 89 specimens were collected throughout the expeditions using ROVs, mainly within active hydrothermal vent fields. Megafaunal specimens were quickly transferred to chilled seawater and photographed, and tissue subsamples or the entire animal were preserved in 96% ethanol for molecular analysis. Onboard photographs of the sampled specimens were included in this manuscript if they showed characteristic details helpful for taxonomic identification. In the laboratory, the specimens were assigned to the lowest taxonomic level possible using a sequenced segment of approximately 650 bp of the cytochrome oxidase subunit I (COI) gene. Molecular samples were used to verify identifications based on images.

Applied open taxonomic nomenclature and technical notes

Note: Scaling of photographs was, in most cases, not possible due to missing lasers or lasers visible on a different focal plane. Only size estimates, based on samples or in relation to known sizes of taxa, are given. The identification of taxa, based only on imagery, is very difficult and many of the taxa presented herein might be new species. Llife traces and the phylum Porifera, with the exception of a single trace listed as poriferan taxon, Paleodictyon nodosum, are excluded from this catalogue. The phylum Porifera was excluded from this megafauna catalogue because of the high diversity of this group and the difficulties to discriminate these morphologically very similar taxa from one another, based on imagery alone without physical samples within the INDEX area.

Some putative taxa presented have an asterisk followed by an additional taxon name in squared brackets as, for example, “Genus species *[Genus species sp. inc.]”. This means that the image shown in the catalogue has the “Genus species” identification level, even though there do exist certain images in Suppl. material 1, where the species level identification remains uncertain. These images are indicated by “*[Genus species sp. inc.]”, but are assumed to belong to this higher ranked identification level. This was applied where only part, but not all, of the imagery samples could confirm a taxonomic group, based on morphological or molecular results (or both). It has been suggested, in these cases, to move the identification rank up to the level where all images could be reliably identified (Horton et al. 2021). Since this meant a loss of accuracy of the generated dataset and omission of valid identifications made, we decided to keep the higher level of accuracy and introduced and defined the use of the asterisk and squared brackets.

Several abbreviations were used in this fauna catalogue following the recommendations for standardisation of imagery-based annotations by Horton et al. (2021). The taxonomic ranks ˈcl.ˈ (“class”), ˈord.ˈ (“order”), ˈfam.ˈ (“family”), ˈgen.ˈ (“genus”) and ˈsp.ˈ (species) indicate the taxonomic rank and are always combined with the open nomenclature (ON) signs ˈindet.ˈ, ˈinc.ˈ or a unique code applied for this taxon (taxon rank (unique code)). Several morphotypes have a unique code in brackets (DZMB_2021_00xx), that has been assigned to all morphotypes where more than one taxon could be distinguished, but not identified to species level, based on the available imagery. These ON signs are defined according to Horton et al. (2021) as follows:

  • The ˈspp.ˈ (“species (plural)”) was used when there is more than one species present within an identified group of organisms, but could not be further distinguished, based on the imagery.
  • The ˈindet.ˈ (“indeterminabilis”) means that no further identification was possible because diagnostic characteristics were not visible. Missing diagnostic characteristics are often related to blurry imagery, low resolution, orientation of the organism and missing physical samples.
  • The ˈinc.ˈ (“incerta”) means that diagnostic characteristics and (or) physical sample were present, but the identification is still uncertain and needs further comparable material for validation.

Table 3 contains all taxa included in this catalogue.

Table 3.

List of all taxa in this fauna catalogue including phylum and the scientific name authority for the taxon. The asterisk and species names in squared brackets means that a taxon has been identified in several images, but a given identification level could not be supported in all images because not every single observation could be supported by morphological or molecular methods or contradictory results of different methods exist. Some putative taxa presented have an asterisk followed by an additional taxon name in squared brackets, as, for example, “Genus species *[Genus species sp. inc.]”, meaning that the image shown in the catalogue has the “Genus species” identification level, with further images, where the species level identification remains uncertain, indicated by “*[Genus species sp. inc.]”. The taxonomic ranks ˈcl.ˈ (“class”), ˈord.ˈ (“order”), ˈfam.ˈ (“family”), ˈgen.ˈ (“genus”) and ˈsp.ˈ (species) indicate the taxonomic rank and are always combined with the open nomenclature (ON) signs ˈindet.ˈ, ˈinc.ˈ according to Horton et al. (2021) or a unique code applied for this taxon (taxon rank (unique code)).
