Seagrass meadow extents derived from field to spaceborne earth observation at Yule Point, Great Barrier Reef, October 2017 to July 2020

Seagrass meadow extent and meadow-scape was mapped using four alternative approaches at Yule Point, a coastal clear water habitat, in the Cairns section of the Great Barrier Reef, between October 2017 and July 2020. Approach 1 included mapping meadow boundaries and meadow-scape during low spring tides on foot using a handheld GPS. Approach 2 was where the meadows were surveyed at low tide with observations from a helicopter, with observational spot-checks conducted at a number haphazardly scattered points. Approach 3 used imagery collected during low spring tides with a UAV at an altitude of 30 m with a resolution of 0.2cm/pixel. Approach 4 used PlanetScope Dove imagery captured on 05 September 2017 and 09 August 2019 coinciding as close as possible to the field-surveys in 2017 and 2019, with 3.7 m x 3.7 m pixels (nadir viewing) acquired from the PlanetScope archive.
This record describes meadow extent data collected using Approach 4 (PlanetScope imagery). View the original metadata record at https://doi.pangaea.de/10.1594/PANGAEA.946604 for the full data collection.

WAMSI Node 3.2.1 - Diversity, abundance and habitat utilisation of sharks and rays - Lagoon and reef edge dive survey data

Snorkel and SCUBA underwater visual surveys were conducted as part of four field trips to Ningaloo in April and June 2007 and August and December 2008. 
The June and August surveys were restricted to the reef edge on SCUBA, while the April and December surveys were mainly on snorkel and in the lagoon. While the original intention was to provide coverage through the different seasons, poor weather conditions coincided with most of the planned fieldwork (including cyclone ‘Nicholas’) resulting in re-scheduling of some trips.
A total of 137 sites were surveyed between Vlaming Head on the northeast of the Cape to Gnaraloo in the southern part of the Marine Park (see thumbnail picture). Of these surveys, 89 were in sanctuary zones and 48 in non-sanctuary zones (sanctuary zones are shown as hatched in the picture).

WAMSI PhD Top-up - 3.9.7 - Hydrodynamic processes in the Ningaloo reef system over a range of space and time scales

As part of the WAMSI PhD Top-up scholarship - the hydrodynamic processes in the Ningaloo reef system over a range of space and time scales was studied.
A coupled wave-circulation numerical model of Ningaloo Marine Park was created.  It used an extensive field data set collected from April - May 2006 in an ~5 km region around Sandy Bay, to validate its performance. The analysis of field data collected on the forereef, reef flat and in the channel revealed a strong correlation between the incident wave height and currents inside the reef lagoon and channel. 
Parameters include wave parameters (wave height, period, direction) and depth average current velocity (ubar and vbar).

Manly Hydraulics Laboratory - Byron Bay Offshore Wave Data Buoy (WAVEBYB)

This is a metadata record for the Byron Bay offshore wave data buoy (station code WAVEBYB) operated by Manly Hydraulics Laboratory (MHL), NSW Office of Environment and Heritage (OEH). The buoy is moored off Byron Bay at a water depth of approximately 65m.
This metadata record includes a down-loadable .pdf summary document which includes a map with numbered deployment locations and a listing of deployment number, location, water depth and deployment period.
Data from October 1976 to October 1999 was gathered by the Waverider system developed by the Dutch company, Datawell. The Waverider system uses an accelerometer mounted in a loose tethered buoy (0.7 or 0.9m in diameter) to measure the vertical accelerations of the buoy as it moves with the water surface. The accelerations are integrated twice within the buoy and the displacement signal so obtained is then transmitted to a shore station where it is processed to provide wave data statistics.
In October 1999 the station was upgraded with a Datawell Directional Waverider buoy. The Directional Waverider buoy utilises a heave-pitch-roll sensor, two fixed X and Y accelerometers and a three axis fluxgate compass to measure both vertical and horizontal motion. An on-board processor converts the buoy motion to three orthogonal (vertical, north-south, east-west) translation signals that are transmitted to the shore station. The directional spectrum is also routinely transmitted to the receiving station for further processing. This buoy also collects sea surface temperature (SST) data from thermistors that are mounted inside the hull of the buoys, at the base of the buoy about 0.5m below the water surface. The wave and SST data are stored on the receiving station PC before routine transfer to Manly Hydraulics Laboratory via email.

Neighbour-stranger relations in the fiddler crab Uca capricornis

A unique relationship exists between neighbouring males and females in the fiddler crab Uca capricornis. This experiment was designed to demonstrate how a male fiddler crab responds to different individuals tethered near to his burrow. The response of a male crab to the neighbour and a stranger (with similar physical characteristics) was observed. The trial ended when the focal male touched the tethered individual (approach), or after 5 minutes passed with no approach (ignore). The order of the two trials (neighbour or stranger) was random. 80 experiments were conducted in total, 20 of each of the following combinations: i) male -- neighbouring male, ii) male -- strange male, iii) male -- neighbouring female, iv) male -- strange female. 
The results indicate that males treat female neighbours differently to male neighbours and intruders (of either sex). They were less likely to approach a female neighbour than an unknown female tethered in the same spot. They were equally likely to approach an unknown female, a neighbouring male and an unknown male.

Growth and age across range extension region of Centrostephanus rodgersii in eastern Tasmania and morphometric comparison of urchins inhabiting kelp versus barrens habitats

The barrens-forming sea urchin Centrostephanus rodgersii has undergone poleward range extension to eastern Tasmania. This data compares growth, morphology, reproductive investment and gonad indices between individuals inhabiting barrens ('barrens-maintaining' urchins') with those found on kelp beds ('barrens-forming' urchins) in north eastern Tasmania.
The data set is comprised of 3 files. The first (Centrostephanus_biometrics_kelp_vs_barrens_urch.xls) compares biometrics of urchins across 3 sites and 2 habitats in eastern Tasmania. The second (Copy_of_Centrostephanus_annual_jaw_growth_increments.xls) compares annual growth increments of urchins in kelp bed and barren habitat including an additional site in south eastern Tasmania (The Lanterns - Tasman Peninsula) to allow comparison of growth across the newly extended range. The third (Jaw_TD_allometery.xlsx) provides a conversion between the allometry of jaw length and test diameter.
Ultimately a generalised growth model for the sea urchin in kelp bed habitat was obtained for eastern Tasmania.

Henderson Island beach debris data 2015

Data on the type, provenance, quantity (density), and rate of accumulation of beach-washed plastic debris were recorded on Henderson Island, a remote, uninhabited island in the South Pacific during 29 May – 15 August 2015. Henderson Island is rarely visited by humans, thus debris on the islands' beaches may act as a proxy for the adjacent South Pacific Ocean. The island was found to contain the highest density of debris anywhere in the world, up to 671.6 items/m2 (mean ± SD: 239.4 ± 347.3 items/m2 on the surface of the beaches. Approximately 68% of debris (up to 4,496.9 pieces/m2) was buried &lt;10 cm in the beach sediment. Up to 26.8 new items/m are thought to accumulate daily.

SeaBASS - The SeaWiFS Bio-optical Archive and Storage System

High quality in situ measurements are prerequisite for satellite data product validation, algorithm development, and many climate-related inquiries. As such, the NASA Ocean Biology Processing Group (OBPG) maintains a local repository of in situ oceanographic and atmospheric data to support their regular scientific analyses. The SeaWiFS Project originally developed this system, SeaBASS, to catalog radiometric and phytoplankton pigment data used their calibration and validation activities. To facilitate the assembly of a global data set, SeaBASS was expanded with oceanographic and atmospheric data collected by participants in the SIMBIOS Program, under NASA Research Announcements  NRA-96 and  NRA-99, which has aided considerably in minimizing spatial bias and maximizing data acquisition rates.  Archived data include measurements of apparent and inherent optical properties, phytoplankton pigment concentrations, and other related oceanographic and atmospheric data, such as water temperature, salinity, stimulated fluorescence, and aerosol optical thickness.

Morphodynamics of Deeban Spit, Port Hacking.

Deeban Spit is in the estuary of the Port Hacking River.  The data collected will be used to study the dynamics of Deeban Spit across three time scales: geological through a review of literature, engineering through GIS spatial analysis of changes in spit volume, and shoal and seagrass area through aerial photography.
The aerial photographs were taken sporadically throughout the period from 1930 to 2006 and monthly throughout the four month period from March to July 2006 of the beach profile survey period. 
In the geological time scale, Deeban Spit has developed through sediment brought to the coast during the post glacial marine transgression (PMT), and the flooding of coastal valleys forming the estuary mouth. The sediment was then reworked into a flood tide delta, and waves, tides, and dredge spoil disposal caused the establishment of the spit itself. Decadally, the spit has oscillated according to shoal movement (which may be dredging and/or current induced) and major storm events, with a mean erosion trend of 117m3 /year. The storm events caused major changes in the beach profile, which varied between the locations along the spit. Similar profile adjustments were observed on a monthly scale, with a greater rate of erosion (mean rate of 18 650m3/year for the 4 month period) possibly due to the occurrence of a 6m storm wave event on 3/6/06) with the ability to cause most of this erosion in one event.

Crayfish and octopus surveys, Ningaloo Reef, Western Australia (WAMSI Node 3 Project 3.1.3)

A series of field trips were made along the entire length of Ningaloo Marine Park (NMP) in May, July, and September 2008. Underwater visual census (UVC) at inner and outer reef sites within both recreational and sanctuary zones (SZ) were undertaken from North West Cape SZ to the Turtle SZ at the southern end of NMP. In total, 132 lobsters from five species were counted from 265 transects and 18 separate locations (58 sites) along the entire coast of the NMP.Sub-tidal surveys on snorkel and SCUBA were used for octopus surveys and were done simultaneously with lobster surveys. In addition to these, inter-tidal surveys were conducted in December 2008 providing total coverage of octopus habitat across a reef profile. In total, just 28 octopus from a single species (Octopus cyanea) were counted from 410 transects (265 subtidal and 145 inter-tidal) and 59 separate sites along the entire coast of the NMP.
 The specific objectives of this project were:1) A report on stock status for targeted invertebrate species along the length of Ningaloo Marine Park including octopus and lobster.2) A characterization of habitats associated with high numbers of targeted species.3) A comparison of stock abundance in relation to differing levels of visitor access.In addition, a further 6 related questions had been put forward as important to the management of the NMP:1) What is the species diversity of invertebrates at representative habitats in the NMP?2) What is the relative abundance of these species and how do they compare with the 'natural' abundance of these species on comparable reefs?3) How does the abundance of these species change over a gradient of historical and human pressure?4) Are current fishing regulations appropriate?5) What should management targets be?6) What species should be monitored regarding these species?

RAN CTD Profile Data - HMAS MERMAID ProjectID: HI544MER_M From: 2014-04-12 To: 2014-06-03

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 90 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI544MER_M from HMAS MERMAID.
The CTD was manufactured by Applied Microsystems Limited and is the "Micro CTD" model. This CTD type is referred to operationally as the MVP200_CTD. This CTD is fitted with a 4 electrode platinized conductivity cell, thermistor temperature sensor and a semiconductor strain gauge pressure sensor.
The CTD sensors are calibrated at the manufacturer Applied Microsystems Limited on a 12-18 month schedule. The CTD temperature sensor is calibrated against 'Hart' temperature standards. The pressure sensor is calibrated using 'Budenburg Deadweight' standards. The conductivity sensor is calibrated using 'Hart' temperature standards and seawater samples of known conductivity.
The CTD sensors are mounted to a fish-shape probe. The probe is controlled by an electric winch (MVP200 type). For downcasts the fish is allowed to free-fall (winch is in 'free-wheel' mode) under its own weight at about 2-3 ms-1 and then is winched back. Data is recorded in downcast and usually in upcast direction at a sampling rate of 25 Hz. The downcast data is of higher quality because sensors encounter undisturbed seawater that flows through the nose of the fish. On the upcast the fish is flipped around (tail first) and the sensors in the nose encounter disturbed flow from the fish tail.
This type of CTD is prone to a phenomenon called 'salinity spiking' caused by a mismatch between the response times of the temperature and conductivity sensor. Data undergoes a salinity de-spiking routine to correct for this. See the history metadata for further details on the salinity de-spiking process.
Raw CTD pressure data is not always monotonic due to transient up/down motion of winch/ship. Raw pressure data is subsetted to give a monotonic (increasing) sequence and then linearly interpolated to 1 decibar pressure intervals. Data is then flagged with quality control flags after visual inspection and comparison to average climatology and historical CTD casts.
