The survey methodology replicates that of the ICES International Herring Larval Survey. 23 stations were sampled in November 2014, December 2014 and January 2015 using a Gull VII high speed plankton sampler.

All surveys were conducted within Brown and May Ltd. Standard operating procedures, in line with ISO 9001, ISO 14001 and OHSAS 18001 accreditation. A Gulf VII high speed plankton sampler was used for sampling herring larvae with a plankton net with a mesh size of 270µm. The amount of water filtered during each haul was measured using a General Oceanics flowmeter mounted inside the nosecone. A second flowmeter was externally mounted on the frame of the sampler. The sampler was fitted with a SAIV A/S SD204 probe to record conductivity, temperature and depth (CTD) measurements. An Applied Acoustics transponder was also fitted to give a real time feed of the sampler depth using an Applied Acoustics Portable Acoustics Modem (PAM 35 10). The transducer was deployed below the water surface using an aluminium pole attached to the side of the vessel to allow a clear â??line of sightâ?? between the transducer and transponder. 5.5.1 The position of the vessel was tracked at all times using a Garmin GPSMap 278 with an EGNOS differential connected to an external Garmin GA30 antenna. Tow start times and positions were taken when the sampler makes contact with the sea surface and tow end times and positions were taken when the sampler returned to the surface. Sample analysis was undertaken by Cefas specialist laboratory staff in Lowestoft. For each station, information was logged on the station number, position, date and time, haul duration, internal and external flowmeter revolutions, bottom and sampler depth, water bottom temperature and vessel direction of tow. The sampler depth was monitored continuously throughout the tow.The dataset contains abundance estimates of larvae less than 10mm, larvae greater than or equal to 10mm and total larvae abundance (number per m2) of Herring and Clupeidae species.
